Abstract
Purpose
The purpose of this paper is to identify smaller wear particles and improve the calculation speed, identify more abrasive particles and promote industrial applications.
Design/methodology/approach
This paper studies a new intelligent recognition method for equipment wear debris based on the YOLO V5S model released in June 2020. Nearly 800 ferrography pictures, 23 types of wear debris, about 5,000 wear debris were used to train and test the model. The new lightweight approach of wear debris recognition can be implemented in rapidly and automatically and also provide for the recognition of wear debris in the field of online wear monitoring.
Findings
An intelligent recognition method of wear debris in ferrography image based on the YOLO V5S model was designed. After the training, the GIoU values of the model converged steadily at about 0.02. The overall precision rate and recall rate reached 0.4 and 0.5, respectively. The overall MAP value of each type of wear debris was 40.5, which was close to the official recognition level of YOLO V5S in the MS COCO competition. The practicality of the model was approved. The intelligent recognition method of wear debris based on the YOLO V5S model can effectively reduce the sensitivity of wear debris size. It also has a good recognition effect on wear debris in different sizes and different scales. Compared with YOLOV. YOLOV, Mask R-CNN and other algorithms%2C, the intelligent recognition method based on the YOLO V5S model, have shown their own advantages in terms of the recognition effect of wear debris%2C the operation speed and the size of weight files. It also provides a new function for implementing accurate recognition of wear debris images collected by online and independent ferrography analysis devices.
Originality/value
To the best of the authors’ knowledge, the intelligent identification of wear debris based on the YOLO V5S network is proposed for the first time, and a large number of wear debris images are verified and applied.

Abstract
Purpose
This paper aims to relate Taoist Yin‐Yang thinking to Western nomology in terms of trust and trust building, seeking to explore the question of how trust impacts on conflict management.
Design/methodology/approach
A moderating model of trust in conflict management is proposed. Investigations and observations using primary and secondary data are described. Three cases are presented to explain the moderating effects of adjusting activities and trust on conflict and negotiation.
Findings
The proposed model was supported. The following findings have been obtained: keeping a balance between adjusting others and adjusting self is a key to resolving conflict; creating and retaining harmony is a bridge that leads both sides in conflict and negotiation to adjust themselves; taking indirect actions through relationships instead of by direct actions through power is a good way to trigger a state of harmony; and trust is shown to be the original driver and source that contribute to adapting actions, harmony and eventually to a win‐win negotiation outcome.
Research limitations/implications
The investigations were limited in time and scope and consequently not conclusive.
Practical implications
This research may provide practical implictions for people and organizations interested in conflict resolution who wish to: take a position that values trust; take indirect actions through relationship instead of direct actions through power; create and retain harmony between both sides in conflict and negotiation; and keep a balance between adjusting others and adjusting self, so to achieve win‐win negotiation outcomes.
Originality/value
This research may enhance the understanding of Taoist Yin‐Yang thinking by linking it with the Western nomology.

Abstract
Purpose
External knowledge is generally believed to be of prime importance to small to medium‐sized enterprises (SMEs). However, a review of the literature shows that no empirical research has looked at knowledge management issues at the inter‐organizational level in SMEs. This paper seeks to report on an empirical investigation with UK SMEs in the service sector to identify their needs and practices regarding inter‐organizational knowledge transfer, and thus provide empirical evidence to support the above belief.
Design/methodology/approach
A two‐tier methodology (i.e. using both questionnaire survey and interview approaches) is deployed to address the main research objectives. A questionnaire survey of SMEs is carried out to investigate their current inter‐organizational knowledge transfer situation and managers' perception on various relevant issues. Then 12 face‐to‐face interviews with SME managers are conducted to further validate key findings drawn from the questionnaire survey.
Findings
The empirical evidence collected from the survey and interviews confirms the general belief that external knowledge is of prime importance for SMEs, and demonstrates that SMEs have very strong needs for external knowledge and inter‐organizational knowledge transfer.
Research limitations/implications
The findings provide very strong underpinning for further theoretical research on inter‐organizational knowledge transfer in SMEs. However, this study has certain limitations: its results may not be applicable to other industrial sectors or the same sector in other countries; or to micro or large companies; nor does it involve cross‐cultural issues.
Originality/value
By adopting a two‐tier research methodology, this study provides more reliable understanding and knowledge on SMEs' inter‐organizational knowledge transfer needs and practices, and fills the gap that exists in the empirical investigations on the subject.

Abstract
Purpose
In this study, suggestions on the protection and development of marine resources, sea area use and management, improvement of laws and regulations, monitoring of marine resources and impact assessment of marine environment are put forward.
Design/methodology/approach
Literature research method.
Findings
A major factor contributing to the decline in fishery resources is excessive fishing. At present, there are many problems to be solved in the exploitation and utilization of marine mineral resources in China. The pollution problem of marine tourism resources is becoming increasingly serious. Overmining of coastal sea resources has led to planning and management failures.
Originality/value
This paper discusses the current situation of marine resource exploitation and protection in China and analyzes the reasons for excessive resource exploitation from three aspects of marine concept, laws and regulations and marine management.

Abstract
Purpose
The purpose of this study is to advance and test a new construct, harmony voice. Furthermore, according to the social influence theory, the relationship between zhongyong, an essential Confucian orientation mode and voice behavior, and the moderating role of coworker’s regulatory focus (promotion focus and prevention focus) has been examined.
Design/methodology/approach
A field study has been designed to test our hypotheses. We used samples of 291 employee–coworker dyads from a variety of organizations in China to test this study’s hypotheses.
Findings
The results of this empirical study show that zhongyong is positively related to harmony voice. Coworkers’ promotion focus strengthens the positive effect of zhongyong on harmony voice, and coworkers’ prevention focus weakens the positive effect of zhongyong on harmony voice.
Research limitations/implications
Traditionally defined voice and harmony voice might cause different risks to the voicer. However, how and what kinds of risks may be differently caused by these two types of voice behaviors have not been examined in this study. Future empirical research can explore the different effects of traditionally defined voice and harmony voice.
Practical implications
Managers responsible for managing Chinese employees should notice the difference in some important ways of thinking between Easterners and Westerners. Specifically, zhongyong may direct people to express issues related to work in ways that are different from those of their Western counterparts. Harmony voice can benefit the Chinese organization without disrupting organizational development.
Social implications
By examining the relationship between zhongyong and harmony voice, we contribute to identifying antecedents of voice by using an emic research perspective.
Originality/value
We made significant theoretical contributions to voice literature. We developed the construct of harmony voice, and we examined the relationship between zhongyong and voice.

Abstract
Purpose
The purpose of this study is to demonstrate that using appropriate values for fictitious parameters is very important in dynamic relation methods. It will be shown that a better scheme can be made by modifying these terms.
Design/methodology/approach
Former research studies have proposed diverse values for fictitious parameters. These factors are very essential and highly affect structural analyses’ abilities. In this paper, the fictitious masses in ten previous well-known schemes are replaced with each other. These formulations lead to the extra 41 different new procedures.
Findings
To compare the skills of the created processes with those of the ten previous ones, 14 benchmark problems with geometrical nonlinear behaviour are analysed. The performances’ evaluations are based on the number of iterations and analysis time. Considering these two criteria, the score of each technique is found for the ranking assessments.
Research limitations/implications
To solve a static problem by using a dynamic relaxation (DR) scheme, it should be first converted to a dynamic space. Using the appropriate values for fictitious terms is very important in this approach. The fictitious mass matrix and damping factor play the most effective role in the process stability. Besides, the fictitious time step is necessary for improving the method convergence rate.
Practical implications
Different famous DR procedures were compared with each other previously. These solvers used their original assumptions for the imaginary mass and damping. So far, no attempt has been made to change the fictitious parameters of the well-known DR methods. As these fictitious factors highly affect structural analyses’ efficiencies, these solvers are formulated again by using new parameters. In this study, the fictitious masses of ten previous famous methods are replaced with each other. These substitutions give 51 different procedures.
Originality/value
It is concluded that the present formulations lead to more effective and favourable methods than the solvers with previous assumptions.

Abstract
Purpose
This paper aims to identify the success factors of communities of practice (CoPs) that will improve knowledge creation (KC) in educational organizations. Today, educational organizations are faced with constant changes in their environment. These changes have forced organizations to view their human capital as knowledge capital to survive and thrive. CoPs can be one of the most important factors to achieve these goals, and it should be considered by educational organizations.
Design/methodology/approach
The present paper tries to identify the success factors of CoPs and examine the impact of the success factors of CoPs in KC. The research method is descriptive. The population of the research consists of students of Payame Noor University as a case study. A questionnaire based on experts’ opinion was designed and more than 35 articles were reviewed. Factor analysis was used to categorize and examine the correlation between success factors of CoPs and KC and, finally, the regression equation based on correlation’ result was formed.
Findings
The results showed six success factors: “organization”, “optimizing interactions”, “infrastructure”, “supporting tools”, “strategy and goals” and “organizational support”. These factors reflect the effective factors in educational organizations attempting to progress in KC should focus. Among these success factors, “strategy and goals” and “organization” have the highest effect on CoPs in this case.
Research limitations/implications
The paper discusses how the success factors of CoPs improve KC in universities as educational organization and how an organization will benefit from these factors. It can help the development of guidelines for educational organizations to increase their community knowledge information. They can also apply the findings of this research to promote the scientific level of their related organizations through reinforcement of CoP practices. In this paper, the authors faced some problems to collect expert’s opinion and also gather the questionnaires.
Originality/value
This paper may have great value to researchers, as well as practitioners involved in knowledge-creation programs in organizations about CoPs and the knowledge-creation field. This research can establish guidelines for Payame Noor University Tehran-North as a case study using the right policies and make changes to the traditional structures of the university, improve and develop the knowledge-creation process and the formation of CoPs. This study can guide managers and, especially, the university managers to provide suitable base to shape COPs, help them emerge and enhance them effectively.

Abstract
Purpose
The purpose of this paper is to reveal the influence of organizational identification (OI) on organizational citizenship behavior (OCB) directed toward organization (OCB-O) and OCB directed toward individuals (OCB-I), and explore the moderating effects of turnover intention (TI) and the differences of the moderating effects of supervisors’ ratings of leader–member exchange quality (LMX-L) and subordinates’ ratings of LMX quality (LMX-S) in the process.
Design/methodology/approach
Based on social exchange theory, this study took administrative staff of private small and medium enterprises in China as population. A paired-samples design was used, and 437 valid paired samples were collected finally. Data analyses were conducted by using structural equation modeling.
Findings
OI indicated a positive influence on both OCB-O and OCB-I. TI showed a negative moderating effect on the positive relationship between OI and OCB-I, but no significant moderating effect on the positive relationship between OI and OCB-O. LMX-L and LMX-S were not in one same direction and showed different moderating levels. LMX-L had no significant effects on the relationship between OI and OCB-O, nor did on the relationship between OI and OCB-I. On the other hand, LMX-S strengthened both the positive relationship between OI and OCB-O, and the positive relationship between OI and OCB-I.
Originality/value
This study explored the relationships from social exchange perspective, found that OCB-O and OCB-I had different formation mechanisms and should be explored as distinct variables, and confirmed that it was necessary to use the paired-samples design when studying dyadic phenomena.

Abstract
Purpose
The purpose of this study is to examine whether individual-level knowledge sharing (in terms of attitudes, benefit estimations, self-efficacy and actualised behaviours) affects individual work performance.
Design/methodology/approach
Hypotheses are tested through structural equation modelling of survey data collected from 595 members of a public organisation.
Findings
The findings confirm the hypothesis that knowledge-sharing propensity impacts positively on knowledge-sharing behaviour. Additionally, knowledge-sharing behaviour mediates the relationship between knowledge-sharing propensity and individual performance. The latter effect is also significant amongst the most highly educated members of the organisation but not among those with the lowest educational levels.
Originality/value
This paper provides insights into the knowledge-sharing–attitude–behaviour–work performance linkage. It thus addresses a relatively neglected area in knowledge management (KM) research, namely, that of individual knowledge behaviours and their performance impact, with an aim to better understand the micro-foundations of KM. It also contributes to knowledge on KM in the public sector.
