Abstract
Purpose
This article aims to study unionisation of foreign companies in China and to evaluate its effectiveness on representing labour rights and interests, so as to explore the relationships between the Chinese unions and other industrial relations actors.
Design/methodology/approach
The article is based on in‐depth interview of key stakeholders from national, regional and company trade unions, as well as company management personnel. An archive study of union and company files is also conducted.
Findings
The Chinese trade union has realised that its interests stem from both the increase of membership dues and expansion of the membership base. Unionisation in transnational corporations (TNCs) is a key approach to achieve the interests of the union, which conducts grassroots mobilisation to counteract non‐operative companies but turns a blind eye on labour interest violations in collaborative firms. From the aspect of the union, the effectiveness of unionisation depends on raising its power leverage by affording fewer duties for the workers. Labour rights and workers' demands are not the structural concern of unionisation in TNCs.
Originality/value
The article challenges the research framework about Chinese unionism, which mainly emphasises a state‐union relationship or draws a corporatism perspective. The article concludes that the power relationship between the union and firm has acted as the key theme of the power struggle among industrial relations actors of China.

This paper aims to study the effect of different rare earth oxide on the tribological properties of polyimide (PI) nanocomposites based on the CNT and GO reinforcements.
Abstract
Purpose
This paper aims to study the effect of different rare earth oxide on the tribological properties of polyimide (PI) nanocomposites based on the CNT and GO reinforcements.
Design/methodology/approach
The PI nanocomposites filled with different rare earth oxide based on the carbon nanotubes and graphene oxide were designed and prepared by hot press sintering. The mechanical and tribological properties of PI nanocomposites were carried out, and their reinforcement mechanisms were discovered.
Findings
Rare earth oxide had a weak influence on the impact strength of PI nanocomposites. Filling La2O3 can dramatically reduce the friction coefficient and wear rate of PI nanocomposites.
Originality/value
The PI nanocomposites filled with rare earth oxide based on the CNT and GO reinforcements were designed, and their mechanical and tribological properties were studied.

Abstract
Purpose
This paper aims to present an example of the measurement of airport efficiency, a topic of great interest in civil aviation today. The methodology used is data envelopment analysis (DEA) and the Malmquist Index. The calculation of airport efficiency with up-to-date data for each period is of great importance in the context of sustainability. The study selected ten airports with high air traffic in Turkey as the sample set. The objective of this study is to evaluate the current state of airport efficiency, identify the sources of inefficiency and make appropriate policy recommendations based on the findings obtained.
Design/methodology/approach
The study is based on DEA and Malmquist Index Analysis. The number of personnel and terminal size data of ten selected decision-making units (DMU) are used as inputs, while passenger, cargo and aircraft traffic data are used as outputs. A five-year period, spanning from 2018 to 2022, is considered as the data set in the study.
Findings
Upon analysis of the data from the ten airports included in the study, it was found that the current input-output combination yielded efficient results, with the exception of certain characteristics, such as the impact of seasonal conditions or tourism. Concurrent with the growth in aircraft, passenger and freight traffic, the number of personnel employed at these airports has also increased. It was concluded that technological efficiency is of paramount importance for each airport, and that investments in technology should be increased.
Practical implications
A separate assessment was conducted for each of the ten airports included in the study sample. Each airport was evaluated in terms of its strengths and weaknesses, and areas of low efficiency were identified. Consequently, more general conclusions were reached than airport-specific evaluations.
Originality/value
In order to ensure the long-term sustainability of the sector, it is essential that the efficiency measurements of airports are calculated using up-to-date data on a regular basis. The results obtained from these calculations provide guidance for the strategic plans to be implemented in the long term, as well as for the solution proposals for operational problems. In this context, this study not only provides information to policymakers and airport managers about the current situation, as it includes recent data, but also contributes to the literature in this sense, as it includes policy recommendations.
