Abstract
Purpose
Based on the social cognitive theory, this research analyzed the helping behavior of leaders and its trickle-down effect on an employee's helping behavior. Additionally, this study analyzed the relationship between an employee's helping behavior and thriving at work.
Design/methodology/approach
Cellphones were used to collect data using the experience sampling method from 74 participants over five consecutive days (N = 370), and the conceptual model was analyzed at the episode level.
Findings
This research examined the helping behavior of employees and its role in mediating the relationship between a leader's helping behavior and an employee's thriving at work. Psychological availability moderates this indirect relationship; and high psychological availability increases the indirect influence of a leader's helping behavior on an employee's helping behavior, which in turn increases employee's thriving at work.
Originality/value
The findings of this research shed light on a new social cognitive mechanism through which the helping behavior of leaders enhances an employee's thriving at work.

Abstract
Purpose
Fastener technology is one of the key technologies of the ballastless track structure, and the spring strip is the key component to realize the fastener function. Based on the fatigue test of the WJ-7 type fastener of the ballastless track in China, it is concluded that the fatigue damage of an elastic strip is the main reason for the decline of service performance of the fastener. The purpose of this paper is to discuss the fatigue life of the fastener.
Design/methodology/approach
First, a DH3818 static strain tester is used to measure the static strain signal in the elastic strip fatigue test, and then the fatigue limit of the WJ-7 elastic strip is calculated. Finally, the fatigue life of the fastener strip is estimated.
Findings
The findings of the paper are as follows: first, the lowest fatigue life with a survival rate of 99 percent should be taken as a reference for the service times of WJ-7; second, the fatigue life of the modified formula found to be short under the same stress amplitude.
Originality/value
The fatigue test is processed by the authors and the results of elastic strip are obtained based on the test. Meanwhile, the corresponding limit value of the fatigue stress amplitude is calculated based on the tested results.

Abstract
Purpose
Water-lubricated rubber bearing is one of the most appropriate bearings for underwater use. The most popular design used widely today is the straight fluted rubber bearing. The special configuration leads to partial hydrodynamic lubrication and low load capacity. A new bearing bush structure with two cavities which is favorable for constructing continuous hydrodynamic lubrication was designed and studied. The paper aims to discuss these issues.
Design/methodology/approach
A new bearing bush structure with two cavities which is favorable for constructing continuous hydrodynamic lubrication was designed. The apparatus for studying the tribological behaviors of the two types of water-lubricated rubber bearings has been devised and established in the paper. The experimental studies on the tribological properties of the rubber bearings have been conducted under different loads and velocities. The eccentricity ratio of the new structure rubber bearing with two cavities was measured in experiment and the load capacity was calculated by numerical simulation.
Findings
The experimental results show that the friction coefficient decreases with increasing velocity; the friction coefficient increases sharply with the rising temperature, the friction coefficient increases at first and then decreases with increasing load for fluted rubber bearings. The numerical results were in good agreement with the experimental results. The numerical results show that complete hydrodynamic lubrication can be formed in the new designed rubber bearing with two cavities. The experimental and numerical results all indicate that there is an appropriate bearing clearance which the friction coefficient is minimum and the load capacity is maximum.
Originality/value
A new bearing bush structure with two cavities which is beneficial to constructing continuous hydrodynamic lubrication film was designed. A new apparatus for studying the tribological behaviors of the two types of water-lubricated rubber bearings has been devised and established. Experimental and numerical study on the new structure rubber bearing were conducted in the paper.

Abstract
Purpose
Drawing upon a dynamic managerial capabilities perspective, this study aims to unpack how and when chief experience officer (CEO) transformational leadership influences firm innovation. Specifically, a moderated mediation model linking CEO transformational leadership to firm innovation, which includes strategic flexibility as a mediator and top management team (TMT) knowledge diversity as a moderator, is theorized and empirically tested.
Design/methodology/approach
The authors conducted a survey of 354 TMT members and 62 CEOs from 62 firms in China’s construction industry to explore these relationships. Path analysis using Mplus 7.4 was undertaken to test our proposed moderated mediation model.
Findings
The results revealed that strategic flexibility mediates the positive relationship between CEO transformational leadership and firm innovation. Additionally, TMT knowledge diversity positively moderates the relationship between CEO transformational leadership and strategic flexibility.
Research limitations/implications
Taken together, these findings help advance and deepen our understanding of the mechanisms through which CEO transformational leadership influences firm innovation and boundary conditions under which CEO transformational leadership influences strategic flexibility. At the same time, this study also contributes to the literature on strategic flexibility and the CEO-TMT interface by revealing the interactive effect of CEO transformational leadership and TMT knowledge diversity on strategic flexibility.
Originality/value
Although the positive influence of CEO transformational leadership on firm innovation has been widely recognized, the specific mechanisms underlying this effect have yet to be fully theorized. This study proposes and tests a nuanced theoretical framework linking CEO transformational leadership to firm innovation via a firm’s strategic flexibility. It also argues that TMT knowledge diversity enhances the indirect effect of CEO transformational leadership on firm innovation through strategic flexibility; that is, this indirect effect is significant when TMT diversity is high, but not when TMT diversity is low.

Abstract
Purpose
This study aims to identify the key factors that influence household pro-environmental behaviors (HPEBs) and explore the differences caused by the same influencing factors between household waste management behavior (HWM) and household energy-saving behavior (HES).
Design/methodology/approach
A meta-analysis was conducted on 90 articles about HPEBs published between 2009 and 2023 to find the key factors. HPEBs were further categorized into HWM and HES to investigate the difference influenced by the above factors on two behaviors. The correlation coefficient was used as the unified effect size, and the random-effect model was adopted to conduct both main effect and moderating effect tests.
Findings
The results showed that attitude, subjective norms, and perceived behavioral control all positively influenced intention and HPEBs, but their effects were stronger on intention than on HPEBs. Intention was found to be the strongest predictor of HPEBs. Subjective norms were found to have a more positive effect on HES compared to HWM, while habits had a more positive effect on HWM. Furthermore, household size was negatively correlated with HWM but positively correlated with HES.
Originality/value
The same variables have different influences on HWM and HES. These results can help develop targeted incentives to increase the adoption of HPEBs, ultimately reducing household energy consumption and greenhouse gas emissions and contributing to the mitigation of global warming.

Abstract
Purpose
The purpose of this paper is to describe a simulation and experimental research concerning the effect of recess depth on the lubrication performance of a hydrostatic thrust bearing by constant rate flow.
Design/methodology/approach
The computational fluid dynamics and finite volume method have been used to compute the lubrication characteristics of an annular recess hydrostatic thrust bearing with different recess depths. The performances are oil recess pressure, oil recess temperature and oil film velocity. The recess depth has been optimized. A test rig is established for testing the pressure field of the structure of hydrostatic thrust bearing after recess depth optimization, and experimental results show that experimental data are basically identical with the simulation results, which demonstrates the validity of the proposed numerical simulation method.
Findings
The results demonstrate that the oil film temperature decreases and the oil film pressure first increases and then decreases with an increase in the recess depth, but oil film velocity is constant. To sum up comprehensive lubrication performance, the recess depth of 3.5 mm is its optimal value for the annular recess hydrostatic thrust bearing.
Originality/value
The computed results indicate that to get an improved performance from a constant flow hydrostatic thrust bearing, a proper selection of the recess depth is essential.

The objective of the present work was to study the influence of chemical compositions of five naphthenic acids (NAs) extracted from Liaohe crude oil on their corrosivity.
Abstract
Purpose
The objective of the present work was to study the influence of chemical compositions of five naphthenic acids (NAs) extracted from Liaohe crude oil on their corrosivity.
Design/methodology/approach
Fourier‐transform infrared spectrometry and electron impact mass spectrometry were used to characterize the chemical structures and compositions if five NAs. The corrosivities of the NAs were assessed by stagnant NA corrosion (NAC) tests. An attempt was made to identify any correlation between the chemical composition of the NAs and their corrosiveness.
Findings
The acidic species in all five NA samples were saturated aliphatic and naphthenic acids and the amount of aromatic and unsaturated acids was negligible. A relationship between the carboxylic acid distribution and the molecular weight was obtained. Most of the carboxylic acids in five NAs contained 0‐3 ring structures. NAs with lower molecular weight and fewer ring structures usually were more corrosive.
Originality/value
The findings have important implications for assessing the corrosivity of acidic crude oils from various resources.
