Hydro-viscous drive (HVD) clutches are widely used in equipment requiring soft start, such as fans and pumps, to transmit torque and adjust speed by changing the gap distance between friction pairs. This paper aims to propose a novel two-parameter evaluation method for HVD during the mixed lubrication stage. The objective is to develop an effective model that establishes the relationship between these parameters and the actual surface topography.

In the presented methods, the fractal features of the real manufacturing surface are calculated based on the power spectrum function by the ultra-depth three-dimensional microscope. After that, the hybrid friction model of the friction plate is established based on mixed elasto-hydrodynamic lubrication theory, boundary friction model and fractal theory. Then the torque and load bearing characteristics of the clutch are obtained, and the influences of the surface fractal features are investigated and discussed. Finally, the Weierstrass–Mandelbrot function is adopted for the surface topography characterization and evaluation.

The results indicate that the proposed method exhibits good accuracy, while the speed difference between the friction pair exceeds 2,500 rpm. It is concluded that this paper proposed a way to evaluate the torque and loading capacity of HVD considering the real manufacturing surface topography and is helpful for surface optimization.

The originality and value of this study lie in its development of a novel torque and load bearing capacity evaluation method for HVD in mixed lubrication stage, considering manufacturing surface topography and describing the real manufacturing surface.

The purpose of this paper is to examine some drivers of users’ participation in online social question-and-answer (Q&A) communities based on social cognitive theory and then identify the underlying mechanism of this process.

This study developed a research model to test the proposed hypotheses, and an online survey was employed to collected data. Totally, 313 valid responses were collected, and partial least squares structural equation modeling was adopted to analyze these data.

This study empirically finds that the outcome expectations (personal outcome expectations and knowledge self-management outcome expectations) are positively related to participation in online social Q&A communities. At the same time, users’ self-efficacy positively influences their participation behaviors. It can not only directly motivate users’ participation, but also indirectly promote participation behaviors through the two dimensions of outcome expectations. Besides, perceived expertise and perceived similarity are two positive and significant environmental elements affecting users’ participation.

This study extends the understanding about how participation behaviors will be motivated in the context of online social Q&A communities. Drawing on the social cognitive theory, constructs were established based on the features of these communities. Meanwhile, some mediating effects in the motivating process were also discussed.

The purpose of this paper is to investigate the mediating effect of felt obligation for constructive change on the relationship between responsible leadership and organizational citizenship behavior for the environment (OCBE) in a China corporate environment, and this paper also analyze the moderated mediating effect of supervisor-subordinate guanxi on indirect relationship between responsible leadership and OCBE via felt obligation for constructive change.

This paper used 380 employee samples to analyze the relationship between responsible leadership and OCBE. Hierarchical regression analyses and structural equation modeling was adopted to analyze the data.

The authors found that the felt obligation for constructive change plays a fully mediating role between responsible leadership and OCBE. The authors also found a positive interaction between responsible leadership and supervisor-subordinate guanxi on felt obligation for constructive change, and then the indirect effect of responsible leadership on OCBE via felt obligation for constructive change was stronger when employees perceived a high-level supervisor-subordinate guanxi.

When responsible leadership stimulates employees to generate a high sense of constructive change, employees are more likely to engage in OCBE. This study provides evidence for cognitive evaluation theory. This study further demonstrated the importance of establishing high-quality supervisor-subordinate guanxi for responsible leaders and subordinates in China.

In the management practice of the organization, the role of responsible leadership should be strengthened in terms of leadership development and, employee training and promotion, and high-quality supervisor-subordinate guanxi help to promote the effectiveness of responsible leadership.

This paper discusses how and when responsible leadership influences OCBE in a China corporate environment.

The purpose of this paper is to find a method for key assembly structure identification in complex mechanical assembly. Three-dimensional model reuse plays an increasingly important role in complex product design and innovative design. Assembly model has become important resource of models reuse in enterprises, which contains certain function assembly structures. These assembly structures implicating plenty of design intent and design experience knowledge can be used to support function-structure design, modular design reuse and semantics analysis for complex product.

A method for identifying key assembly structures in assembly model is presented from the viewpoint of assembly topology and multi-source attributes. First, assembly model is represented based on complex network. Then, a two-level evaluation model is put forward to evaluate importance of parts assembled, and the key function parts in assembly can be obtained. After that, on the basis of the function parts, a heuristic algorithm upon breadth first searching is given to identify key assembly structures.

The method could be used to evaluate key function parts and identify key assembly structures in complex mechanical assembly according to the specific circumstances.

The method can not only help designers find the key assembly structure in complex mechanical assembly model, facilitate the function-structure designing and semantics analyzing, and thereby improve the efficiency of product knowledge reuse, but also assist in analyzing influence scope of key function part changing and optimization of the assembly process for complex mechanical assembly.

The paper is the first to propose a method for key assembly structure identification in complex mechanical assembly, where the key function parts can be evaluated through a two-level evaluation model, and the key assembly structures are identified automatically based on complex network.

This paper aims to examine the effect of consumer inertia – a tendency to adhere to prior purchase decisions despite the existence of preferable alternatives – on the relationships between switching costs and customer retention, and explain the controversy within them in the context of budget hotels.

An empirical test was conducted via structural equation modelling based on 337 self-administered questionnaires from customers at six of Chinese popular budget hotels.

Consumer inertia was a significant mediator between switching costs and customer retention. Specifically, consumer inertia completely mediated the effects of financial switching costs on customer retention, but partially did between procedural switching costs and customer retention. By introducing consumer inertia, the explanatory power of customer retention improved significantly by 19%.

This paper clarifies the effects of multiple dimensions of switching costs on customer retention via the mediating role of consumer inertia and partly addresses the inconsistency in the prior studies from an inertia perspective.

The purpose of this paper is twofold: first, to examine a customer orientation mechanism through which abusive supervision influences retail salespeople’s job performance; and second, to investigate how abusive supervision’s effects may be moderated by the same leader’s use of contingent punishment and contingent reward.

Two studies provide consistent findings. Study 1 used the field survey data from 129 salespeople in 42 retail stores. The proposed moderated mediation model was estimated using the random coefficient modeling technique. Findings were replicated in Study 2, in which data were collected from a sample of 679 US retail salespeople recruited through M-Turk.

Results from both studies show that abusive supervision reduces salespeople’s job performance through lowering their customer orientation. Furthermore, the use of contingent punishment from the same supervisor buffers abusive supervision’s detrimental effect, whereas the use of contingent reward augments it.

The issues the authors address in this research have significant implications for the literature of abusive supervision and retail selling. First, the authors contribute to the abusive supervision literature by pointing it out that the negative effect of abusive supervision can spill over to organizations’ external stakeholders, namely, customers. Previous research on abusive supervision has mainly focused on how abused subordinates exhibit hostile acts directed against the supervisor, coworkers and the organization (Tepper et al., 2017), with little attention paid to abusive supervision’s impact on organizations’ external stakeholders such as customers. This research fills the void by placing impaired customer-orientation as a critical consequence of abusive supervision. Second, this research tests a contingent self-regulation impairment model of abusive supervision and advances our understanding about how the same supervisor’s functional leadership behaviors (contingent reward/punishment) may set contingencies for the effect of abusive supervision on employee outcomes. This investigation clears the doubts about whether the use of functional leadership behaviors along with abusive supervision buffers or aggravates the detrimental effect of the latter. Finally, this study’s findings shed new insights to marketing practitioners, especially in understanding how salespeople may vent their stress on the customers when being abused by their supervisors. Without this in mind, supervisors may not be aware of the consequences of their abusive behavior and may even develop an illusion that such a practice worked. This research shows that abusive supervision can lower employees’ customer orientation, which will hurt the company in the long run.

The findings intend to provide important guidelines for companies to develop effective workshops and training programs to combat the detrimental effects of abusive supervision in the retailing industry. For example, the findings shed new insights in understanding how employees may vent their stress on the customers when being abused by their supervisors. Without this in mind, supervisors may not be aware of the consequences of their abusive behavior and may even develop an illusion that such a practice worked. Another important managerial implication of this research is that the use of contingent reward after mistreating subordinates can backfire. Supervisor abuses, followed by a contingent reward, send an inconsistent signal to the employee that creates confusion and strain. Inconsistent actions from the supervisor also produce ethical tensions that reduce customer-oriented behaviors and a company’s ability to serve the customer (Friend et al., 2020). These training programs are important methods to combat the detrimental effects of abusive supervision in the workforce.

This research draws on the contingent self-regulation impairment model as an overarching framework to unpack the relationship between abusive supervision and salespeople’s job performance. Integrating three research streams (i.e. abusive supervision, leadership reinforcement and retail selling), this study proposes customer orientation as a novel mechanism and sheds light on how abusive supervision interplays with contingent punishment/reward to impact salespeople’s outcomes.

Reducing production auxiliary time is the key to improve the efficiency of the existing mixed-flow assembly line. This paper proposes a method combining improved genetic algorithm (GA) and Flexsim software. It also investigates mixed-flow assembly line scheduling and just-in-time (JIT) parts feeding scheme to reduce waste in production while taking the existing hill-drop mixed-flow assembly line as an example to verify the effectiveness of the method.

In this research, a method is presented to optimize the efficiency of the present assembly line. The multi-objective mathematical model is established based on the objective function of the minimum production cycle and part consumption balance, and the solution model is developed using multi-objective GA to obtain the mixed flow scheduling scheme of the hill-drop planter. Furthermore, modeling and simulation with Flexsim software are investigated along with the contents of line inventory, parts transportation means, daily feeding times and time points.

Theoretical analysis and simulation experiments are carried out in this paper while taking an example of a hill-drop planter mixed-flow assembly line. The results indicate that the method can effectively reduce the idle and overload of the assembly line, use the transportation resources rationally and decrease the accumulation of the line inventory.

The method of combining improved GA and Flexsim software was used here for the first time intuitively and efficiently to study the balance of existing production lines and JIT feeding of parts. Investigating the production scheduling scheme provides a reference for the enterprise production line accompanied by the quantity allocation of transportation tools, the inventory consumption of the spare parts along the line and the utilization rate of each station to reduce the auxiliary time and apply practically.
