Abstract
Purpose
This paper aims to analyze the effectiveness of the subject librarian literacy training and put forward suggestions for the improvement of the subject librarian literacy training based on the satisfaction degree survey for the CALIS III Subject Librarian Literacy Training.
Design/methodology/approach
On the basis of the satisfaction degree survey for the CALIS III Subject Librarian Literacy Training, this paper elaborates on the design of the survey, analyzes effectiveness of the training according to the survey results, and further advances suggestions for the enhancement of the subject librarian literacy training.
Findings
As an essential part of the library user service, subject services are highly demanding of subject librarians' literacy and capabilities. The subject librarians should thus own great abilities to be qualified for the innovative subject service work. Although the CALIS III Librarian Literacy Training and Qualification Certification Program, a vital executive program, has made great achievements, the training still needs to be further improved concerning the schedules, teaching atmosphere, training forms, training content, etc., to enhance the subject librarians' ability, raise the service standards and promote the fast and sound development of librarianship in China.
Originality/value
This paper offers detailed information on how to design a satisfaction degree survey for the subject librarian literacy training, analyzes the effectiveness of the librarian literacy training, and finally makes suggestions for the enhancement of the subject librarian literacy training.

Abstract
Purpose
This study aims to investigate the relationship between inventory flexibility, digital transformation, supply chain concentration, and productivity in the context of Chinese manufacturing enterprises.
Design/methodology/approach
Empirical analysis was conducted using data from listed Chinese manufacturing firms spanning from 2013 to 2022. The study employs a moderated model to examine how digital transformation influences the connection between inventory flexibility and productivity. Additionally, a moderated moderation model is utilized to explore the role of supply chain concentration in moderating the relationship among inventory flexibility, digital transformation, and productivity.
Findings
The study reveals a significant positive correlation between inventory flexibility and productivity, underlining the importance of flexible inventory management. Digital transformation moderates this relationship, with digital transformation enhancing the impact of inventory flexibility on productivity. Supplier and customer concentration also positively moderate this connection, suggesting a complementary relationship with digital transformation.
Practical implications
These findings offer valuable insights for managers and policymakers, emphasizing the need for a flexible approach to inventory management that considers the evolving digital landscape and supply chain dynamics.
Originality/value
This study contributes to the literature by providing empirical evidence of the nuanced relationship between inventory flexibility, digital transformation, supply chain concentration, and productivity in Chinese manufacturing enterprises. It underscores the importance of integrating digital transformation and supply chain concentration initiatives with flexible inventory management to optimize productivity in the business landscape.

Abstract
Purpose
The purpose of this paper is to study the friction and wear properties of CrNiMo steel pin against brass disk in different oxygen fractions. CrNiMo steel is currently widely used in industry and military fields for its excellent performance in some severe environments. The atmosphere and temperature are key factors affecting the wear behaviors of CrNiMo steel. The study aims to make better use of CrNiMo steel in different atmospheres.
Design/methodology/approach
Friction and wear experiments were conducted using a pin‐on‐disk tribometer equipped in an atmosphere controllable chamber. The chamber allows switch between vacuum and gas mixtures of N2 and O2. The oxygen content was managed by magnetic coupling flow meter. The sliding speed of 1, 2, 3, 4 m/s and the applied sliding contact load of 5, 6.5, 8, 9.5 N were used in friction test. In order to obtain information on the wear mechanisms, the worn surface of the pin was examined by scanning electron microscopy and energy dispersive X‐ray spectroscopy.
Findings
A close dependence is clearly shown of the friction and wear on the content of oxygen gas in elevated temperature. Increasing the content of oxygen in the atmosphere under higher normal load condition is beneficial to friction reduction of the steel/brass pair. Different wear mechanisms were found with a transition from the adhesive wear in nitrogen, to a mixed adhesion and oxidation wear when increasing the content of the oxygen in the atmosphere.
Originality/value
This paper provides a reference for the similar steel used in severe environments.
