This paper examines how and why online daters, differentiated by gender, strategically self-present in online dating profiles when pursuing two competing goals: attracting potential daters and avoiding detection as a liar.

A survey and a content analysis were employed to test four hypotheses.

The results revealed that seeking to project an attractive image in online dating was significantly associated with acquisitive self-presentation. The online daters adopted falsification more than any other strategies, and women were more likely than men to embellish their self-presentation, especially their physical appearance.

The findings clarify people's mate selection processes in light of the interpersonal deception theory (IDT) and the information manipulation theory (IMT) as well as take an evolutionary psychological perspective on computer-mediated communication. For practitioners, they provide a more nuanced picture of deceptive communication in online dating and, for online daters, can guide the adaptation of their online behaviors.

The purpose of this paper is to propose a wheel/rail mixed lubrication model to study the water lubrication behavior of wheel/rail contact interface.

The numerical simulation method is applied in this paper. A deterministic mixed lubrication model considering surface roughness and transient state is established. The quasi-system numerical and finite difference method are used for numerical solution. The model is verified by comparing with the experimental data in the literature under the same conditions.

Under wet conditions, the change of train speed will change the lubrication state of the wheel/rail contact interface. With an increasing speed, the average film thickness and the film thickness ratio increase, while the adhesion coefficient, the contact load ratio and the contact area ratio decrease. When the creep ratio increases from 0% to 0.5%, the wheel/rail adhesion coefficient and subsurface stress increase sharply. With the increase of axle load, the average film thickness decreases and the adhesion coefficient increases.

This paper aims to improve the mixed lubrication theory by analyzing the characteristics of wheel/rail friction and lubrication, so as to provide some guidance and theory for train driving behavior.

Using the deterministic model, the lubrication state of the wheel/rail contact interface affected by various external factors and the adhesion behavior of wheel/rail progressive process from boundary lubrication to mixed lubrication are studied.

Drawing on the political theory of leadership and the input‐process‐output model the purpose of this paper is to examine the link between leader political skill and team performance by focusing on the mediating role of team communication and the moderating role of team task interdependence.

The authors collected three waves of data from 80 teams across four business units and employed hierarchical regression modeling and the moderated path analysis approach suggested by Edwards and Lambert to test the moderated mediation model.

Leader political skill was found to positively influence team performance via promoting the quality of team communication. Moreover, team task interdependence moderates the relationship between leader political skill and team communication, such that the relationship is stronger when team task interdependence is high rather than low.

First, the paper adopts the measuring scales developed in the western organizational context to investigate the relations and phenomena existing in the Chinese organizational context. Future research should adopt the indigenous measuring scales to investigate the relations and phenomena existing in the Chinese organizational context. Second, both political skill and team performance were reported by the team leader, which might lead to common source bias. Future research should allow team members to rate leaders' political skill and the team leaders' supervisors to provide evaluation of team performance.

Owing to its importance to team performance, political skill is one of the critical skills that leaders should make efforts to develop. When companies recruit leaders for work teams, they should put more attention on the political skills of the candidates. Moreover, companies should cultivate a cooperative team climate to facilitate team communication.

Although Ahearn et al. suggested that leader political skill has positive effect on team performance, they did not empirically examine the specific process and mechanism through which the positive effect occurs. This study argues team communication is a critical mechanism that bridges leader political skill and team operations and outcomes as well. The study adopts longitudinal research design and collects multi‐source data to test the authors' model. The study also complements past research by investigating both the mediating and moderating mechanisms in the leader political‐team performance linkage.

Drawing on social exchange theory and traditional Chinese leadership theory, this research examines employees' perceptions of corporate social responsibility (CSR) using a multilevel mediation model. It also examines the possibility that meaningful work mediates the relationship between perceived CSR and work engagement.

Survey data were collected from 605 employees of 103 departments across 35 companies in Taiwan. Multilevel path models and hypotheses were tested using Mplus structural-equation modeling software.

The results show that department-level CSR perceptions were positively related to employee-level work engagement and that CSR was a mediating factor between department managers' moral leadership and employee-level work engagement. Additionally, meaningful work played a cross-level mediating role between CSR perceptions and work engagement.

For organizational managers, these findings imply that enterprises should practice CSR and guide their employees in its correct interpretation. They also reinforce the idea that department leaders should behave ethically, because this will encourage their employees to develop positive perceptions of the company's CSR implementation and thus to be more engaged in their work. Lastly, incorporating CSR programs into training materials and encouraging employees to actively participate in such programs' development, deployment and evaluation should help make work meaningful for employees and further enhance their engagement with it.

This study explains how a cross-level mechanism connects department-level moral leadership to employee-level work engagement in a Chinese cultural context.

The purpose of this study was to test the mediating effect of psychological entitlement in the relationship between perceived overqualification (POQ) and workplace ostracism. In addition, the authors posited that POQ would interact with task interdependence to influence psychological entitlement and indirectly affect workplace ostracism.

Using data collected in three waves from 450 workers in a state-owned enterprise, the authors tested the proposed moderated mediation model.

POQ increased workplace ostracism through the mediation of psychological entitlement. Moreover, task interdependence buffered the positive effect of POQ on psychological entitlement.

When recruiting, managers should be careful about hiring employees who are too above the job requirements to lessen employees' POQ and lower its negative impact. In addition, they could reduce the feeling of being ostracized for overqualified employees through increasing task interdependence.

Existing research on antecedents of workplace ostracism had mainly focused on the ostracizers, while largely ignoring the victims. Moreover, of the few studies on the victims of ostracism, most focused on inherent employee characteristics or external environmental factors, while little research attention has been given to employees' subjective perceptions. The present study is among the first to examine whether employees' POQ and individuals' self-perception that their skills, knowledge and abilities exceed the job requirements would lead to being ostracized and if so, how and when.

The purpose of this paper is to investigate the tribological performance and mechanisms of BN/calcium borate nanocomposites (BCBNs) as additives in lubricating oil.

BCBNs were prepared by heterogeneous deposition method. And the morphology and structure of samples were analysed by transmission electron microscopy, Fourier transform infrared spectra and X-ray powder diffraction pattern. The maximum non-seizure load (PB) of samples was tested using four-ball friction tester. The average friction coefficients and wear tracks were obtained. In addition, tribological mechanism was also investigated using optical microscope, energy dispersive spectroscopy and X-ray photoelectron spectroscope.

It was found that the nanocomposites present core-shell nanostructure with the thickness of shell around 12 nm and the diameter of particles 100-200 nm, and tribological tests indicate that the PB value of BCBNs was increased by 113 per cent, whereas the average friction coefficient was decreased by 23.6 per cent and the bloom’s wear area was also decreased by 25.2 per cent.

This paper involves investigation on tribological properties and mechanism of the BCBNs with core-shell structure.
