Abstract
As an optimal microstructure of pipeline steels, acicular ferrite is widely found in steels used in oil and gas pipeline transportation because it possesses both high strength and good toughness. In this paper, the microstructure of acicular ferrite and its continuous cooling transformation (CCT) diagrams of six steels with different carbon and alloy additions have been studied by using dilatometry, optical metallography. And the effects of different hot deformation processes on the CCT diagrams and microstructures have also been studied. Furthermore, the effects of microalloyed elements and hot deformation on continuous cooling transformation have been discussed. The results show that lower carbon content and alloy additions such as Mn, Nb, Ti, Mo, Ni and/or Cu in steels will promote the formation of acicular ferrite. The hot deformation promotes the acicular ferrite transformation and refines the microstructures of final products.

Abstract
Purpose
Teacher well-being has been a concern, but there has been a lack of research on how teacher leadership can contribute to teacher well-being in a high-accountability context and a hierarchical education system such as that of China, particularly through the meditating roles of trust in the leader and teacher efficacy. Therefore, the purpose of this study was to understand the relationship between teacher leadership and teacher well-being while exploring the mediating roles of trust in leaders and teacher efficacy in this relationship.
Design/methodology/approach
Using structural equation modeling (SEM) and bootstrap methods with valid answers from 1,144 teachers in 25 primary schools in 1 Chinese city, this study mainly answered three questions: Is there a significant relationship between teacher leadership and teacher well-being? Is there a significant mediating effect of trust in leaders on the relationship between teacher leadership and teacher well-being? Is there a significant mediating effect of teacher efficacy on the relationship between teacher leadership and teacher well-being?
Findings
This study reported a positive relationship between teacher leadership and teacher well-being. This study also found positive mediating roles for trust in leaders and teacher efficacy in the relationship between teacher leadership and teacher well-being in a high-accountability and hierarchical system like that of China.
Originality/value
This study provides an understanding of the transferability of teacher leadership theories across cultures and has practical significance for educational practice in high-accountability and hierarchical education contexts similar to that of China.

Abstract
Purpose: Despite the significance of filial piety in intergenerational relationships and its important influence on parental health and well-being, few studies have explored the personal meaning of filial piety to older parents. This qualitative study aims to address this question.
Design: Responses to an open-ended question of “What makes a filial child in your view?” from a sample of 432 older parents in a rural Chinese county were collected face-to-face and analyzed using content analysis.
Findings: The personal meaning of filial piety varies. Seven broad themes emerged. These include widely persistent traditional filial piety beliefs (Be obedient, Respect, and Maintain frequent contact and show emotional care), filial piety values similar to filial obligations described in Western cultures (Help older parents when in times of need and Be a good citizen and take good care of themselves and their families), and traditional filial piety norms in the absolute form (Take care of every aspect of the parents’ life and Provide financial and material support to parents). Themes were also compared with dimensions of the intergenerational solidarity model.
Originality: Findings reflect the coexistence of traditional and modern filial values in relation to participants’ interpretation of filial piety, indicating that traditional filial piety beliefs are fading even in one of the least developed areas in China. Implications for interventions enhancing offspring’s filial performance are discussed.
Research limitations: Future studies on the understanding of filial piety from the perspective of offspring are warranted to draw a holistic picture of this topic.

Abstract
Purpose
The aims of this study are to conduct a systematic review of public–private partnership (PPP) studies published from 2009 to 2019, to compare the results with Ke et al. (2009) who reviewed the PPP literature published from 1998 to 2008, and to trace the evolution of the PPP knowledge in the past two decades. This study also presents the possible directions that the PPP research may go towards in the future, arguably.
Design/methodology/approach
This study carried out a top journal-based search to identify the quality PPP articles published from 2009 to 2019. A total of 12 top-tier construction journals were systematically searched in the database of web of science (WOS), from which 279 PPP articles were identified for review.
Findings
The number of the identified articles, the titles of the journals, institutions, the most cited papers, and prevalent research methods were analyzed and compared. The existing PPP studies in construction journals were classified into seven streams. Through analysis of the PPP research status and gaps, five future research directions were revealed.
Originality/value
This study contributes to the current body of knowledge by revealing the research trend of PPP from 2009 to 2019. It presents the change of PPP development trend in the past decade through comparison with Ke et al. (2009). It also reveals the major research streams and points out the directions that the PPP research may go towards in the future. Moreover, this study is helpful to the practice as well. It can enhance the practitioners' understanding of the PPP development in the past decade. In addition, it identified the research institutions contributing the most in the area of PPP, which may serve as valuable reference for practitioners to locate the best institutions for consultancy or collaboration.

Abstract
The growth of China’s economy during the 1990s has both shaped and reflected changes in the span and function of the country’s shipping connections both within Asia and with the rest of the world. Although sea-land developments within China have been studied, less attention has been paid to the wider global implications stemming from the transformation of the country’s maritime geography during a decade of further market reforms and greater integration into the world economy. Consequently, there is a need to comprehend how China’s state-owned shipping industry has been reorganized during the 1990s to meet the new requirements, with special reference to the country’s liner shipping connections between and within Asia respectively. More purposely, these topics are addressed by examining changes in the organization, approach and set of connections of the state-owned China Ocean Shipping (Group) Company (Cosco) and its post-1993 offshoot COSCO Container Lines Company Ltd (Coscon). This review provides a springboard for a detailed analysis of shifts in both extra- and intra-Asian shipping patterns between 1990 and 2000 and consideration of their strategic implications. Finally, short-sea shipping is defined and the phenomenon’s operational strengths and weaknesses discussed.

Abstract
The international Communist movement is experiencing great turbulence. Some Western media state with certainty that Lenin′s dream has come to an end, but Chinese practice has proved the contrary conclusion. High efficiency is characteristic of and intrinsic to Communism. The productivity of labour is the most important thing in the success of a new social system. Socialist business has just begun and will create much higher productivity than capitalism.

Abstract
Purpose
The purpose of this paper is to report on a three‐year PMI2 project for the British Council in 2008, one of seven to develop and strengthen partnerships with Chinese institutions in employability and entrepreneurship. Involving a partnership between Leeds Metropolitan University England and the Zhejiang University of Technology Hangzhou, China, the aim has been to analyse the Hangzhou and Zhejiang economies and examine current Chinese company requirements for skills and talent and their implications for teaching and learning and graduate supply. This was intended to strengthen the existing partnerships at a civic level between Leeds and Hangzhou and the successful MA in Trade and Finance run by the two universities.
Design/methodology/approach
The paper draws on preliminary interview studies in China of Hangzhou companies in different industrial sectors to analyse the skill and talent needs of such companies, their demands for graduate talent in particular and their views about the adequacy of the supply of that talent from local and national universities.
Findings
The paper clarifies the relationship between talent demand and supply in China, especially with regard to graduate talent, and presents an original analysis of the skill needs of the Hangzhou economy.
Originality/value
The paper suggests ways in which universities in Zhejiang and China generally could strengthen their engagement with businesses over talent demand and supply, and how they could develop courses and programmes that more effectively bridge the gap between universities and businesses.

Abstract
Purpose
Given the effects of natural and social factors, data on both the supply and demand sides of electricity will produce obvious seasonal fluctuations. The purpose of this article is to propose a new dynamic seasonal grey model based on PSO-SVR to forecast the production and consumption of electric energy.
Design/methodology/approach
In the model design, firstly, the parameters of the SVR are initially optimized by the PSO algorithm for the estimation of the dynamic seasonal operator. Then, the seasonal fluctuations in the electricity demand data are eliminated using the dynamic seasonal operator. After that, the time series after eliminating of the seasonal fluctuations are used as the training set of the DSGM(1, 1) model, and the corresponding fitted, and predicted values are calculated. Finally, the seasonal reduction is performed to obtain the final prediction results.
Findings
This study found that the electricity supply and demand data have obvious seasonal and nonlinear characteristics. The dynamic seasonal grey model based on PSO-SVR performs significantly better than the comparative model for hourly and monthly data as well as for different time durations, indicating that the model is more accurate and robust in seasonal electricity forecasting.
Originality/value
Considering the seasonal and nonlinear fluctuation characteristics of electricity data. In this paper, a dynamic seasonal grey model based on PSO-SVR is established to predict the consumption and production of electric energy.
