The wear of an abrasive single-crystal diamond (SCD) grit affects the machining quality of the sapphire wafer. This paper aims to investigate the influence of crystallographic orientation on the wear characteristics of SCD grit scratching on sapphire.

The wear characteristics of two SCD grits (SCD100 and SCD111) with different crystallographic orientations were systematically investigated. The wear mechanism involved in the scratching process was explored. The wear morphology, scratching forces and friction coefficient during the scratching process were measured and analyzed.

The experiment results show that the wear progress of the two SCD grits is obviously different. The wear resistance of SCD111 grit is greater than that of SCD100 grit in normal wear stage. However, the SCD100 grit could remove more sapphire material than SCD111 grit. The SCD grits mainly sustain extrusion stress and shear stress during scratching on sapphire. The crystallographic orientation of SCD grits plays a significant role in the wear progress during scratching on sapphire.

The results of the experimental studies could provide a theoretical foundation for improving the fabrication of abrasive diamond tools.

Mechanical wear is the main wear form of abrasive single crystal diamond (SCD) grit. The mechanical wear of SCD grit has a significant influence on the tool life and machining quality. This paper aims to investigate the influence of grit–workpiece contact form on the mechanical wear characteristics of SCD grit.

Three different grit–workpiece contact forms, which involved point/line/face contact forms, are investigated to reveal the wear mechanism of SCD grit scratching on Ta12W. The wear morphology, wear volume and scratching forces are measured, and the stress models of different contact forms are analyzed.

The results show that mechanical wear mainly occurs in the grit–workpiece contact area and increases gradually from contact area to entire SCD grit. The scratching forces vary with the mechanical wear progress of SCD grits. The SCD grit with point contact form is the most prone to produce wear. The SCD grit with face contact form can remove more material volume than the other two SCD grits, and it is the most wear resistant. The stress state is closely related with the mechanical wear of SCD grit. The contact form has a significant influence on the mechanical wear of SCD grit.

The results of this study can provide a theoretical basis for the fabrication of abrasive tools.

This paper offers a practical conceptualization and understanding of grit, exploring what grit adds to the organizations and how to develop it at an individual and organizational level.

The article is based on Duckworth’s and colleagues’ research on grit and later developments, especially those related to the empirical check on the relationships between grit and individual accomplishment and company performance. It combines a literature review overview and conceptual developments with practical application.

Grit is a two-factor personality trait positively correlated to conscientiousness that promotes and predicts superior achievement and accomplishment. Developing a nurtured grit capacity requires promoting learning, coaching, executive intelligence, and positive interactions at work within a critical thinking environment.

Following the conceptual model developed, further research is needed about the relationships between growth mindset, critical thinking, grit, grit and resilience, and how individual grit becomes organizational.

A superior accomplishment can be achieved by integrating and promoting grit employees within the company. Besides, grit is also a good predictor of happiness, rising above, hardiness, and other desirable attributes. Grit requires the development of a critical-thinking environment and executive intelligence workforce.

Superior accomplishment through life helps to develop this goal in the workplace. The pandemic magnitude is partly due to a lack of critical thinking and grit.

This paper guides managers and professionals to implement a grit company strategy grounded on some reputation research without abstracted theoretical disquisitions.

The purpose of this paper is to examine the effect of grit (consistency of interest and perseverance of effort) on entrepreneurial career success (career satisfaction, perceived career achievement and perceived financial attainment) through the role of resilience.

The study was cross-sectional, and the data were collected using questionnaires from 111 entrepreneurs in Nigeria who have been in business for over five years and were selected using purposive sampling technique. The study used Smart-PLS to assess the measurement and structural model.

The perseverance of effort was related to all the aspects of career success as well as resilience. But consistency of interest was positively related to only perceived financial attainment. It also predicted resilience. Resilience was also related to all the facets of career success. All three mediation hypotheses were supported.

The study delivered fascinating understandings into the structures of grit. The Western conceptualisation of grit may not be valid in a collectivist society where consistency is not that very much considered.

The study helps to further validate grit in the entrepreneurship field; the construct is a facilitator of entrepreneurial action and an indispensable source of energy that can revitalise the entrepreneur along the arduous road to success.

The two components of grit can have a dissimilar influence on different outcomes – as prior investigations, although recognising that the two components are conceptually dissimilar, have rarely studied them so empirically.

The major purpose of the present study is to investigate the contribution of academic resilience in accounting for two motivational and attitudinal constructs ? Grit and positive orientation and also probe the predictive power of all these constructs in academic achievement of university students in the midst of the pandemic COVID-19.

521 university students participated in an online survey. To measure academic resilience, a scale designed and validated by Kim and Kim (2016) comprising 26 items was employed. The scale contains five sub-factors: perceived happiness, empathy, sociability, persistence and self-regulation. Grit was assessed via an 8-item scale comprising two facets: perseverance of effort (PE) and consistency of interest (CI). It was designed by Duckworth and Gross (2014). Positive orientation was determined through positivity scale developed by Caprara et al. (2010), consisting of eight items.

The results of structural equation modeling (SEM) revealed that resilience positively and significantly predicted both grit (β = 0.56, t = 6.41) and positive orientation (β = 0.54, t = 6.35). Resilience also predicted academic achievement directly (β = 0.71, t = 9.12) and indirectly via its impact on grit and positive orientation. It was also found that positive orientation and grit are positively and highly associated (β = 0.77, t = 9.28).

The pandemic COVID-19 brought about substantial changes in university students' education and their overall life style. Many university students around the globe experienced virtual education. Balancing personal and academic roles in these unprecedented conditions seems to be a tough challenge for every university student.

The purpose of this paper is to examine the influence of grit, which is the tendency to pursue long-term goals with perseverance and continuing passion, on leaders’ self-reported behavior in terms of role modeling and innovating, as well as inspiring, empowering and supporting followers.

Data were collected from an international sample of 3,702 leaders in work and non-work contexts. They reported their level of grit and how frequently they engaged in five leadership practices. Moderation analysis was used to test the influence of grit on leadership behaviors across contexts.

High grit leaders reported more frequent role modeling and innovating behaviors, but less inspiring behavior. Grit’s effect on empowering behaviors depended on the context; grit caused leaders to empower followers more in non-work contexts, but not in work-related ones.

That grit is an important predictor of leadership behavior yields both practical and theoretical implications. For practice, the results suggest that grit is a desirable trait in managers, corresponding with their greater use of various leadership behaviors. For theory, the results suggest that part of the effect of traits in leadership arises from influencing the frequency with which leaders engage in particular behaviors.

This is the first study to examine grit’s role in leadership, and it has practical and theoretical implications. For practice, the results suggest that grit is a desirable trait in leaders, but one which requires unique supports from the leader’s environment. For theory, the results begin to fill an important gap. It is well-established that personality influences leadership outcomes, but it remains uncertain how and when. The current study suggests how, since traits influence the frequency with which leaders engage in particular behaviors, and begins to define when, highlighting differences between work and non-work contexts.

The purpose of this paper is to test the interactive effects of grit (e.g. supervisor and employee) and politics perceptions on relevant work outcomes. Specifically, the authors hypothesized that supervisor and employee grit would each demonstrate neutralizing effects when examined jointly.

Three studies (N’s=526, 229, 522) were conducted to test the moderating effect across outcomes, including job satisfaction, turnover intentions, citizenship behavior and work effort. The authors controlled for affectivity and nonlinear main effect terms in Studies 2 and 3 following prior discussion.

Findings across studies demonstrated a unique pattern differentiating between grit sources (i.e. employee vs supervisor) and outcome characteristic (i.e. attitudinal vs behavioral). In sum, both employee and supervisor grit demonstrated neutralizing effects when operating in politically fraught work settings.

Despite the single source nature of data collections, the authors took steps to minimize potential biasing factors (e.g. time separation, including affectivity). Future research will benefit from multiple sources of data as well as a more expansive view of the grit construct.

Work contexts have grown increasingly more political in recent years primarily as a result of social and motivational factors. Hence, the authors recommend that leaders investigate factors that minimize its potentially malignant effects. Although grit is often challenging to cultivate through interventions, selection and quality of work life programs may be useful in preparing workers to manage this pervasive source of stress.

Despite its practical appeal, grit’s impact in work settings has been under-studied, leading to apparent gaps in science and leadership development. Creative studies, building off the research, will allow grit to maximize its contributions to both scholarship and employee well-being.

The purpose of this paper is to investigate the relationships between grit, unethical behavior and job stress among business-to-business salespeople.

The empirical analysis includes 240 business-to-business salespeople. Structural equation modeling is used to test the study’s hypotheses.

Results suggest grit is directly related to less frequent unethical behavior and customer-directed deviance. Neutralization techniques positively moderate the relationship between salesperson grit and both unethical behavior and customer-directed deviance. Grit is indirectly related to job stress through the positive relationship between unethical behavior and job stress.

Given research on grit in sales is relatively new several opportunities to pursue additional research in this area are presented.

Sales leaders may benefit from administering the salesperson grit scale as part of the screening process and developing grit among salespeople through training and coaching. Sales leaders should emphasize the negative impact of adopting neutralization techniques (excuses) in condoning unethical behaviors. The indirect effect of grit in reducing job stress through ethical behaviors underscores potential ways to mitigate costly and detrimental sales outcome losses.

This study develops a novel framework to explore the relationships between grit and unethical behaviors as moderated by neutralization techniques (excuses); examines an additional component of grit not previously considered in some studies of salespeople; and investigates whether these relationships increase a previously unexplored outcome – job stress.

This conceptual paper explores how the activation of the individual-level trait grit can explain variance in successor willingness to take over leadership of the family firm.

Drawing from trait activation and situation strength theories, the authors develop a framework to examine the interactions of the two dimensions of grit (passion and perseverance) on the successor's willingness to take control of the family firm.

The authors identify how the grit dimensions would interact with the situational cues present during the succession process to predict the successor's willingness to take control of the family firm and offer testable propositions to guide future empirical work.

The authors help to address the growing need for additional microfoundational family firm research by drawing insights from organizational behavior theories and personality research and apply them to the family firm succession process.

The concept of grit has been receiving increased attention in recent years. Grit is a trait that enables individuals to persevere while facing challenges and obstacles in life, sometimes “winning at any cost”. The purpose of the study is to understand how ethical views may vary among different groups of people segmented on grittiness. Our key argument is that grittier segment is more inclined towards Machiavellian factors (amorality, desire for control, desire for status, distrust of others) and materialism.

Data derived from self-administered questionnaires completed by convenience samples of Indonesians living in Daerah Istimewa Yogyakarta (DIY), a region commonly considered as the miniature of Indonesia. Turning to market segmentation tools (n = 467), we first segment people based on their level of grittiness and, subsequently, investigate each segment's perception towards various Machiavellian factors (amorality, desire for control, distrust of others) and materialistic attitudes.

The study identified three segments of grittiness: The Least Gritty (the Good), The More Gritty (the Bad) and The Most Gritty (the Ugly). The results of this study showed the dark side of grit. Individuals with higher grit traits are more likely to behave unethically which could be referred to as “bad” and “ugly”. To help them succeed, cheating and lying are more likely considered acceptable by gritty individuals compared to less gritty “good” individuals.

Merely focussing on grit–be it grit promotion or training–may produce individuals who achieve success at all costs and disregard ethical values. An implication from the study is not to discourage developing grit in individuals but instead to add and emphasise ethical components. This implication is especially critical for educators and managers developing grit as a part of their activities.

The results of this study will have important theoretical implications and managerial implications educators balancing the consequences of teaching grit, but also for managers interested in understanding employees' level of grit within their workplaces along with ethical considerations.
