Abstract

Purpose

Little is known about when younger employees’ intergenerational knowledge transfer (IGKT) – behaviors of acquiring knowledge from older employees – improves their innovative work behaviors (IWB), especially in hospitals. Taking into consideration the moderating roles of individual absorptive capacity (AC) and organization size, this study aims to develop a theoretical model to account for the associations of both online and offline IGKT with younger employees’ IWB.

Design/methodology/approach

The model was tested with a survey of 202 Chinese younger doctors (40 years old and below). Partial least squares structural equation modeling (PLS-SEM) was used to analyze the data.

Findings

The results showed that both online IGKT and offline IGKT have significant positive relationships with younger doctors’ IWB. Individual AC can strengthen the relationship between offline IGKT and IWB, and organization size can weaken the relationship. However, both individual AC and organization size do not significantly moderate the relationship between online IGKT and IWB.

Originality/value

The findings extend the understanding and application of individual-level knowledge-based view and media synchronicity theory by exploring the relationship of knowledge acquisition from older doctors through both online and offline communication channels with younger doctors’ IWB.

Abstract

Purpose

Drawing on social information processing theory, this study investigates how platform leadership influences employees’ innovative behavior. Specifically, we propose a theoretical model that incorporates creative self-efficacy as a mediator and organizational identification as a moderator.

Design/methodology/approach

Multisource data were collected in three waves from 304 employees and their 65 leaders in China.

Findings

Hierarchical linear modeling (HLM) results reveal: (1) a positive association between platform leadership and subordinates’ innovative behavior; (2) creative self-efficacy as a mediator in the relationship between platform leadership and subordinates’ innovative behavior and (3) organizational identification as a moderator in the indirect relationship between platform leadership and subordinates’ innovative behavior through creative self-efficacy, with the indirect effect being stronger when organizational identification is high than when it is low.

Originality/value

From a cross-level perspective, our findings revealed the underlying mechanisms and boundary conditions under which platform leadership influences followers’ innovative behavior.

Abstract

Purpose

Babbitt bush is easy to cause severe adhesive wear due to unexpected journal fall. This paper aims to improve wear resistance of Babbitt bush.

Design/methodology/approach

A soft/hard hybrid surface mircoprofile of Babbitt alloy/steel was fabricated by a technology of laser texture combined with hot-pressing. The friction and wear performances of bare steel (steel-h), Babbitt bush on steel (steel-s) and Babbitt filled in dimples of steel (steel-hs) were conducted on a ball-on-disc tester under dry and lubricated conditions.

Findings

The results showed that wettability of steel-hs was enhanced by forming soft/hard hybrid surface. Compared with steel-s, the stability of friction coefficient curve of steel-hs was improved without increasing coefficient friction. The wear resistance of steel-hs was remarkably enhanced under dry and lubricated conditions.

Originality/value

The originality of this paper is as following: to improve the tribological properties and to prolong service life of steel-s, soft/hard hybrid surface of Babbitt filled in dimples of steel substrate was successfully fabricated by laser texturing combined with hot-pressing. This paper showed that the lipophilicity of steel-hs was best among those of steel-s and steel-h. Babbitt alloy as a soft filler on dimples of steel substrate improved anti-wear of steel-s remarkably. It provides a new way to fabricate Babbitt as bushing on steel substrate.

Abstract

Purpose

This paper aims to propose a system for generating actionable knowledge from Big Data and use this system to construct a comprehensive knowledge base (KB), called GrandBase.

Design/methodology/approach

In particular, this study extracts new predicates from four types of data sources, namely, Web texts, Document Object Model (DOM) trees, existing KBs and query stream to augment the ontology of the existing KB (i.e. Freebase). In addition, a graph-based approach to conduct better truth discovery for multi-valued predicates is also proposed.

Findings

Empirical studies demonstrate the effectiveness of the approaches presented in this study and the potential of GrandBase. The future research directions regarding GrandBase construction and extension has also been discussed.

Originality/value

To revolutionize our modern society by using the wisdom of Big Data, considerable KBs have been constructed to feed the massive knowledge-driven applications with Resource Description Framework triples. The important challenges for KB construction include extracting information from large-scale, possibly conflicting and different-structured data sources (i.e. the knowledge extraction problem) and reconciling the conflicts that reside in the sources (i.e. the truth discovery problem). Tremendous research efforts have been contributed on both problems. However, the existing KBs are far from being comprehensive and accurate: first, existing knowledge extraction systems retrieve data from limited types of Web sources; second, existing truth discovery approaches commonly assume each predicate has only one true value. In this paper, the focus is on the problem of generating actionable knowledge from Big Data. A system is proposed, which consists of two phases, namely, knowledge extraction and truth discovery, to construct a broader KB, called GrandBase.

Abstract

Purpose

Copper-graphite (Cu/C) is a type of seal material that has been widely used in liquid rocket engines and with normal metal pairs, has a high wear rate under liquid oxygen lubrication. In this study, bearing steel disks were subjected to a high-temperature oxidization and phosphating progress to create an oxidized tricresyl phosphating film (OTCP) film, using tricresyl phosphate (TCP) as the phosphating solvent. It is hoped that the surface wear rate and friction coefficient can be reduced by this method.

Design/methodology/approach

This study aim to form an anti-wear film on the surface of bearing steel, which can significantly improve the lubrication performance of Cu/C and bearing steel. The surfaces of bearing steel disks were dried to remove surface water and then put on a heating plate with a magnetic stirrer and a blue glazed oxide film obtained by heating the disks in the air at 200°C for 1 h. To create the OTCP film, bearing steel disks with a blue glazed oxide film were cleaned ultrasonically three times in ethanol and then placed in baths of TCP. After heating for 2 h at 120°C, excess TCP liquid was removed from the disks using ethanol, leaving an OTCP film on the disk surface.

Findings

It was found that steel coated with an OTCP film demonstrated better tribological performance (lower coefficient of fiction and wear rate) when pairing with Cu/C than either oxidized or untreated bearing steel. Additional chemical reactions occur when the oxide disk is immersed in TCP and the FePO4 film is formed after heating. Additionally, the OTCP film coated steel displayed good corrosion resistance, as confirmed by electrochemical corrosion tests. This finding demonstrates the potential for this process in the aerospace industry.

Originality/value

The preparation of OTCP films via high-temperature oxidization and phosphating of bearing steel was demonstrated, with the tribological properties of the OTCP film being investigated alongside those of the original surface and an oxidized film surface. The fabrication of OTCP films is easily scaled up and exhibits significant advantages as a new technology for applications in mechanical contact seal lubrication.

Abstract

Purpose

Different aspects of the globalisation of Chinese basic education have been examined in recent studies. This paper aims to contribute to this research base by examining the relationship between global quality assurance and evaluation (QAEVAL) trends and reforms in the Chinese basic education system.

Design/methodology/approach

Relevant research literature in English and Chinese was reviewed to assesses whether a movement of increasing convergence with global QAEVAL policy contents and policy instruments has taken place in China following the introduction of the so-called “equality education”. A guiding theory regarding the basic features of QAEVAL was used to conceptually structure the findings of the authors.

Findings

The findings indicate that several subtle convergences are evident in China with global trends in QAEVAL, but a few notable exceptions are also evident.

Research limitations/implications

Albeit the research indicates certain convergence, the authors acknowledge that further research is still needed to examine causal mechanisms of QAEVAL policy convergences and the processes and logic through which global trends are localised.

Originality/value

Both the importance of QAEVAL in global education governance as well as China’s importance to world affairs are increasing. However, so far, the effects of QAEVAL policies on China’s education system have not been thoroughly examined. This paper can serve as a concise starting point for examining the topic more deeply.
