Abstract

Purpose

The purpose of this paper is to identify key antecedents of work-family enrichment (WFE) for Chinese workers in China. The paper adopts the Chinese cultural perspectives (i.e. philosophy of Confucian: Chinese family orientation and collectivism) as well as traditional Chinese philosophies of life as a whole.

Design/methodology/approach

This is a conceptual paper. Therefore, this section does not apply.

Findings

The key antecedents of Chinese WFE have been identified and presented in the conceptual framework. Testable propositions have also been developed and presented in this paper.

Practical implications

The conceptual framework showing the identified key antecedents of Chinese WFE highlights the necessity for the corporate leaders to rethink the ways to promote well-being and productivity of Chinese workforce in China. Meanwhile, managers should rethink about WFE among Chinese employees and regard employees as a whole person rather than just a worker with certain skills or abilities.

Originality/value

This is the first paper to propose the concept of life enrichment by examining the antecedents of WFE particularly from the Chinese philosophical and cultural perspective.

Abstract

Purpose

The purpose of this paper is to verify whether the disclosure of other comprehensive income has effectively improved the transparency of corporate disclosure and thus effectively reduced earnings management.

Design/methodology/approach

In total, 391 valid samples are selected from more than 860 listed companies of Shanghai A shares in 2009, excluding finance and insurance categories, those with incomplete data and samples whose other comprehensive income is zero.

Findings

The results show that other comprehensive income has played an important role in all comprehensive income and significantly affected earnings management. The disclosure of other comprehensive income is negatively related to earnings management, that is, disclosure of other comprehensive income can curb earnings management to some extent in order to make the public better understand the performance of a given company.

Research limitations/implications

Owing to the short period of time for the issuance of Accounting Standards No. 3, there are fewer comparable data. Besides, only companies from Shanghai A shares during 2009 are surveyed without Shenzhen Share. Finally, there should be a dialectic and mutual relation between earnings management and other comprehensive income.

Practical implications

The paper's findings suggest that it is necessary to carry out the disclosure to improve the transparency of the accounting information, so as to curb earnings management and improve earnings quality to some extent, which provides valuable reference for the government's decision.

Originality/value

Finance [2009] 8 on the issuance of Accounting Standards No. 3 issued by Ministry of Finance Republic of China in June 2009 explained that all listed companies are required to disclose “comprehensive income” and “other comprehensive income” under the item “earnings per share” in the income statement. Based on the 2009 annual report of listed companies, the paper elaborates descriptive statistics related to the composition of other comprehensive income. Empirical research is conducted to verify the effect of the new policy. In a word, the paper selects a big number of samples to conduct the study in order to make more valuable reference.

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.

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

This paper aims to propose some suggestions for libraries and other digital reading service institutions to improve the utilization rate of e-books, based on the theoretical and empirical analysis of the perception behaviour characteristics of e-book selection under the allocation of limited cognitive resources.

Design/methodology/approach

From the perspective of key perception points, this paper studies the key perception points of selecting e-books through the experimental method and explores the influence of subject factors (users’ characteristics, users’ needs) on users’ e-book perception behaviour.

Findings

College students have selective attention in the process of selecting e-books. They will choose some important contents of e-books, such as title, book introduction, author, catalogue, reader comments, others’ recommendations, read leaderboard, to perceive and there is an obvious difference in perception intensity. Different personal traits and reading needs have a great influence on users’ perception points. Libraries and other digital reading service institutions should provide promotion information based on key perception points of e-books, develop personalized e-book service and promotion and optimize the expression of key perception points of e-books.

Originality/value

This paper presents a valuable study attempting to introduce cognitive resource theory into the field of digital reading service, which proves that users also have limited cognitive resource allocation in the process of selecting digital books.

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

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

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.

Abstract

Purpose

The purpose of this paper is to develop an environmentally safe aqueous polymer‐isocyanate (API) wood adhesive for structural uses with whey protein isolate (WPI) that is a by‐product of cheese making.

Design/methodology/approach

The API formulations with whey proteins denatured at different heating temperatures and times, WPI/polyvinyl alcohol (PVA) denaturing processes, PVA contents and nano‐CaCO3 (as filler) contents were investigated and optimised according to the JIS K6806‐2003 standard.

Findings

A whey‐protein based API adhesive was developed which had 28 h boiling‐dry‐boiling wet compression shear strength 6.81 MPa and dry compression shear strength 13.38 MPa beyond the required values (5.88 and 9.81 MPa, respectively) for structural use of commercial standards. The study also indicated that the thermal denaturation of 40 per cent WPI solution at 60‐63°C could unfold the globular structure of whey protein to some extent and therefore improve the bond strength and bond durability of whey‐protein based API adhesive; the additions of PVA and nano‐CaCO3 as filler had a significant effect on the bond strength and bond durability of whey‐protein based API adhesive.

Research limitations/implications

The thermally denatured WPI solutions (40 wt%) incline towards being decayed by moulds if not properly formulated.

Practical implications

Owing to the good bond strength and durability and environmental safety, the optimised whey‐protein based API adhesives have greater potential for commercial applications, especially for the structural wood bonds.

Originality/value

A novel API wood adhesive for structural use was developed using whey proteins that are often regarded as a waste due to their relatively small molecules and compact globular structures.

Abstract

While much has been written on operational aspects of hotel food and beverage functions, the literature on career paths and background characteristics of successful food and beverage directors is quite sparse. A survey was distributed to all food and beverage directors of four and five star hotels in America to obtain a clear understanding of the career histories of food and beverage directors and to determine if there are any distinguishing characteristics in terms of demographics, education or experience which are possessed by successful food and beverage directors. Nearly all of the food and beverage directors reported having ambitions for higher positions, with hotel general manager the most preferred higher position. The results of the study have implications for hospitality education curriculum development and human resource planning in the luxury full service hotel industry.
