This paper aims to develop a stable gel-type lubricant emulating commercial conditions. This encompassed rheological and tribological assessments, alongside field trials on the Medellín tram system.

The gel-type lubricant with graphite and aluminum powder is synthesized. Rheological tests, viscosity measurements and linear viscoelastic regime assessments are conducted. Subsequently, tribological analyses encompassing four-ball and twin disc methods are executed. Finally, real-world testing is performed on the Medellín tram system.

An achieved lubricant met the stipulated criteria, yielding innovative insights into the interaction of graphite and aluminum powder additives under varying tests.

Novel findings are unveiled regarding the interaction of graphite and aluminum powder additives in tribological, rheological and real-world trials. In addition, the wear behavior of polymers is observed, along with the potential utilization of such additives in tramway systems.

This research studies the development of the evolving dynamic system model and explores the important elements or factors and what detailed attributes are the main influences model in achieving the success of a business, industry and management. It also identifies the real and major differences between static and dynamic business management models and the detailed factors that influence them. Later, this research investigates the benefits/advantages and limitations/disadvantages of some research studies. The studies conducted in this research put more emphasis on the capabilities of system dynamics (SD) in modeling and the ability to measure, analyse and capture problems in business, industry, manufacturing etc.

The research presented in this work is a qualitative research based on a literature review. Publicly available research publications and reports have been used to create a research foundation, identify the research gaps and develop new analyses from the comparative studies. As the literature review progressed, the scope of the literature search was further narrowed down to the development of SD models. Often, references to certain selected literature have been examined to find other relevant literature. To do so, a supporting tool (that connects related articles) provided by Google Scholar, Scopus, and particular journals has been used.

The dynamic business and management model is very different from the static business model in complexity, formality, flexibility, capturing, relationships, advantages, innovation model, new goals, updated information, perspective and problem-solving abilities. The initial approach of a static system was applied in the canvas business model, but further developments can be continued with a dynamic system approach.

Based on this study, which shows that businesses are developing more towards digitalisation, wanting the ability to keep up with the era that is moving so fast and the desire to increase profits, an instrument is needed that can help describe the difficulties of the needs and developments of the future world. This instrument, or tool of SD, is also expected to assist in drawing future models and in building a business with complex variables that can be predicted from the beginning.

This study will contribute to the SD study for many business incubator research studies. Many practical in business incubator management to have a benefit how to achieve the business performance management (BPM) in SD review.

The significant differences between static and dynamics to be used for business research and strategic performance management. This comparative study analyses some SD models from many authors worldwide. Their goals behind their strategic business models and encounter for their respective progress.

Drawing on attribution theory, this study aims to examine how and when abusive supervision affects insubordination, focusing on employees’ attribution bias related to leader gender.

Two mixed-method studies were used to test the proposed research framework. Study 1 adopted a 2 (abusive supervision: low vs high) by 2 (leader gender: male vs female) by employee gender-leadership bias quasi-experiment. A sample of 173 US F&B employees completed Study 1. In Study 2, 116 hospitality employees responded to two-wave, time-lagged surveys. They answered questions on abusive supervision and gender-leadership bias in Survey 1. Two weeks later, they reported negative external attribution (embodied in injury initiation) and insubordination.

Hayes’ PROCESS macro results verified a three-way moderated mediation. The three-way interaction among abusive supervision, leader gender and gender-leadership bias affects external attribution, increasing insubordination. Employees with high leader–gender bias working under female leaders make more external attribution and engage in subsequent insubordination in the presence of abusive supervision.

This study is one of the first, to the best of the authors’ knowledge, that examines the mediating role of external attribution of abusive supervision. Second, this research explains the gender glass ceiling by examining employees’ attribution bias against female leaders.

The main purpose of the current research is to examine affective and cognitive mechanisms by which the trickle-down effect of work engagement from leader to follower takes place.

The current research consisted of two independent studies. In study 1, an experience sampling method was used (N = 1,321 data points from 171 participants) to test within-person effects. In study 2, the authors recruited 266 employees working in 61 teams with two data collections one month apart, to test between-team effects among variables.

In two independent studies, leaders' work engagement resulted in followers engaging in surface acting (an affective process) and developing self-efficacy (a cognitive process), which in turn resulted in followers' work engagement.

The current research provides some clarifications to the literature on work contagion of engagement by examining dual mechanisms. In particular, although previous research emphasized the negative aspects of surface acting, the current research suggests that surface acting can be potentially helpful by facilitating the contagion effect of work engagement leaders to followers. Further, this research also examines the facilitative role of self-efficacy in mediating the relationship between a leader's work engagement and followers' work engagement. Finally, the authors conducted two independent studies that used different research designs, and results were consistent across the two studies, which can provide evidence for the robustness of the results.

The purpose of the current research is to examine the crucial role of employees' perception of an incivility norm in predicting supervisors' incivility behaviors, which in turn, results in employees enacting incivility toward their coworkers and employees' emotional exhaustion.

In Study 1, an experience sampling method (a daily-diary approach) in which 143 male participants from several construction sites completed a total of 1,144 questionnaires was used . In Study 2, cross-sectional data from 156 male employees working in a manufacturing organization was collected. In Study 3, a quasi-experiment was conducted in which 33 and 36 employees were assigned to the intervention and control groups, respectively.

In Studies 1 and 2, it was revealed that employees are likely to experience their supervisor’s incivility behaviors when perceiving such incivility behaviors are more acceptable within the organization (incivility norm). Further, once employees experience incivility from their supervisor, they are more likely to enact incivility toward their coworkers and experience emotional exhaustion. In Study 3, changing organizational policies via implementing grievance procedures was effective in improving the study’s outcome variables.

Incivility norms predict some negative work outcomes such as incivility behaviors as both a victim and instigator, and emotional exhaustion. Further, reducing an adverse organizational norm (i.e. incivility norm) via instituting grievance procedures was effective in reducing incivility behaviors and emotional exhaustion.

This study aims to empirically test the influence of pull factors on the intention to engage in Muslim-friendly travel. This study proposes a distinct path between Islamic attributes and emotional value and scepticism, along with destination image and its functional value. This study also proposes the role of halal awareness in moderating the relationship between Islamic attributes and scepticism.

This study used a quantitative approach using an online survey. The authors purposively selected younger individuals who had travelled inside the country at least three times during the past five years. With a total of 416 valid responses, this study used variance-based partial least squares to test the hypotheses.

The results show that intention to engage in Muslim-friendly travel is positively influenced by emotional and functional values, but negatively by scepticism. Emotional value and scepticism are influenced by Islamic attributes, whereas functional value is influenced by destination image. More specifically, halal awareness is proven to moderate the relationship between Islamic attributes and scepticism, in which individuals with a higher level of halal awareness tend to be less sceptical about halal offerings.

This study supports a previous study in which emotional and functional values are considered differently by consumers. Furthermore, the dual role of Islamic attributes, as pull factors, is confirmed, providing a deeper understanding of its influence on emotional value and scepticism. To the best of the authors’ knowledge, this study is also the first to investigate the role of halal awareness in increasing the level of scepticism among Muslim consumers.

This paper explores key factors influencing high-performing, sustained growth, high-tech small- and medium-sized enterprises (SMEs) in South Korea.

A qualitative study is adopted to explore seventeen founder owner-managers of high-tech SMEs who sustained consistent employment growth, greater than the industry average, for seven years. Within the sample, those with higher (10% or over) employment compound annual growth rates (CAGRs) over this period are also compared to those with lower rates.

The study suggests that proactive approaches, such as flexible organization, risk management, fast decision-making and international market entry, are seen as important contributing factors to sustained growth. These findings contribute to a better theoretical and empirical understanding of sustained high-tech SME growth, in a country with a strong entrepreneurial and internationally competitive information technology sector. Also, collaboration across the SME was perceived as making an important contribution to staff development and growth, consistent with stewardship theory.

The sample is based on successful high-tech SMEs, so there are limitations in extrapolating results to other types of firms, sectors or countries.

Key factors identified in this study can be considered by entrepreneurs seeking to achieve sustainable business. These also provide improved understanding for policymakers into the complexity of factors related to sustained and high growth of technology-based SMEs, which many countries are keen to foster to aid national economic growth.

The research provides new evidence exploring the diverse perspectives of founder owner-managers, on the sustained growth and failure in South Korean high-tech SMEs, and how these have changed since the inception of their business.

This research aims to gain a holistic understanding of how video conferencing (VC) apps' media characteristics influence individuals' perceptions of VC apps and, ultimately, their use and continued use in professional settings.

A conceptual research model is developed by integrating constructs from media synchronicity theory (MST), social presence theory and the unified theory of acceptance and use of technology (UTAUT2) model, as well as ubiquity, technicality and perceived fees. Structural equation modeling (SEM) is used to empirically test the conceptual model using data collected from 252 working professionals from the European Union.

The results reveal that while performance expectancy (PE) and facilitating conditions (FC) are fundamental to VC app use, these factors alone do not explain the use and continuing use of VC apps in the professional context. Media characteristics that include synchronicity, social presence, and ubiquity are equally crucial to professionals using VC apps. It also confirms the moderating effect of convergence on the relationship between synchronicity and PE and the moderating effect of technicality and perceived fees on the relationship between ubiquity and FC.

For researchers, the study offers insights into the extent to which technological and socially derived characteristics of VC apps influence the routine tasks undertaken by professionals in virtual work settings. For practitioners, recommendations pivotal to the use of VC apps are presented to promote higher acceptance and improved well-being of the professional workforce.

Women's participation in the workforce and in managerial positions, which has led to greater diversity, reconstructs professional perceptions and preferences. The purpose of this research is to examine “Work Outcome Preferences” among men and women according to organizational status and the impact of other demographic factors.

The Meaning of Work (MOW) questionnaire was filled by 1,161 men and women employees in organizations: 744 workers, 256 junior managers and 161 middle managers. To examine the hypotheses, authors conducted an analysis of variance (ANOVA) test and a linear regression analysis for women and men.

The gender differences regarding work outcomes preferences decreases with career promotion. Further, the higher the organizational status, the higher the need for interesting and satisfying work among both men and women. Among women, the higher the organizational status, the higher the need for status and prestige and for serving society and the lower the need for interpersonal contacts and income.

Better understanding of the preferred outcomes among women and men in the three organizational statuses and the impact of promotion and varied demographic variables can help in the planning of material and non-material reward systems and methods suitable to the different sub-groups.

As far as authors know, there is not a single study focusing on the differences between narrow career stages such as workers, junior and middle managers according to gender regarding work values/work outcome preferences.
