Alternating current (AC) corrosion is a type of corrosion that occurs in buried pipelines under AC stray current interference, which can increase the hydrogen embrittlement sensitivity of pipelines. However, rare research works have been conducted on the hydrogen permeability characteristics of pipeline steel under AC stray current interference. The purpose of this paper is to study hydrogen permeation behavior of X80 steel under AC stray current interference.

In this paper, the hydrogen permeation behavior of X80 steel under AC interference is studied by AC hydrogen charging experiment in a dual electrolytic cell. The relationship between hydrogen evolution rate and hydrogen permeation flux is studied using the gas collection method. The difference between AC hydrogen permeability and direct current (DC) hydrogen permeability is also discussed.

The anodic dissolution caused by AC corrosion promotes the chemical desorption reaction of the adsorbed hydrogen atoms on the surface, reducing the hydrogen atom absorption ratio by 70%. When the AC is smaller than 150░ A/m², the hydrogen permeation process is controlled by the hydrogen atom generation rate, and the hydrogen permeation flux increases with the increase in hydrogen atom generation rate. When the AC exceeds 400░ A/m², the hydrogen permeation process is controlled by the absorption ratio. The hydrogen permeation flux decreases with the decrease in the absorption ratio. Under AC interference, there is a maximum hydrogen permeation flux that linearly correlates to the H⁺ concentration in the solutions.

The high-strength steel is very sensitive to hydrogen embrittlement, and X80 steel has been widely used in oil and gas pipelines. To date, no research has been conducted on the hydrogen permeation behavior of pipeline steel under AC interference, and the hydrogen permeability characteristics of pipeline steel under AC interference are not clear. The research results of this paper are of great significance for ensuring the intrinsic safety of high-strength pipelines under AC stray current interference.

Examines the key elements that are involved in managing successful turnarounds. An analysis of the turnaround strategies of more than ten global companies revealed that these strategies incorporated similar sequential processes: identification of problem and need for change; replacement of incumbent CEO; major cost‐cutting attempts; refocusing on core businesses, and reinvesting for the future.

Based on the perspective of cognitive psychology, this paper takes the M&A events of Chinese A-share listed enterprises from 2008 to 2015 as the research samples, and then empirically analyzes the influence of managerial overconfidence on M&A premium under the special circumstances in China and tests the moderating effect of debt capacity between managerial overconfidence and M&A premium.

This paper selects the M&A events of all A-share listed enterprises from 2008 to 2015 as the total samples. In view of the fact that the data in this paper are unbalanced panel data, so this paper uses the LR test, LR test and Hausman test to filter the mixed OLS model, fixed effect model and random effect model. Finally, using the random effect model for empirical testing reduces the endogeneity of the model.

The study shows that managerial overconfidence is positively correlated with M&A premium; at the same time, compared with the state-owned enterprises, the relationship between managerial overconfidence and M&A premium is more significant in private enterprises. Further study shows that debt capacity can strengthen the relationship between managerial overconfidence and M&A premium, to be specific, the larger the debt capacity is, the stronger the positive relationship between managerial overconfidence and M&A premium will be. Moreover, after considering the influence of agency cost and financing expense, and conducting endogenous test and robust test, this research’s conclusions remain the same.

This research also has some limitations. Some M&A announcements are incomplete, and the target has more information missing, resulting in a decrease in the number of samples, which may affect the accuracy of the conclusions. This paper does not address the research of the economic consequences of M&A, namely, the impact of managerial overconfidence and debt capacity on M&A performance. This is one of the future research directions for this paper.

The conclusions of this paper provide new theory evidence for Chinese enterprises' M&A decision-making.

First, enterprises should gradually improve corporate governance structure and governance mechanisms to guide more stakeholders to participate in corporate governance, and also they should strengthen the pre-evaluation, in-process control and post-supervision of managers' behavioral decisions to prevent irrational M&A caused by managerial overconfidence. Especially in private enterprises, this issue should be paid more attention. Second, enterprises should make full use of the debt governance function of creditors and improve the creditors' supervision mechanism for managers' decision-making behavior.

The innovation value and increment contribution of this paper may include the following aspects: the conclusions of this paper expand the research boundary of the relationship between managerial overconfidence and M&A premium, and enrich related literature about debt capacity and the influence of debt capacity on M&A decision-making, and also provide new theory evidence for Chinese enterprises' M&A decision-making. In a word, this research is a beneficial supplement and extension for existing research.

This paper aims to study the effect of the establishment of bankruptcy courts on bond issuance market. This paper helps to predict that the introduction of bankruptcy courts in China can mitigate price distortions caused by the implicit government guarantees and promote the development of the high-risk bond market.

This paper exploits the staggered introduction of bankruptcy courts across cities to implement a differences-in-differences strategy on bond issuance data. Using bonds issued in China between 2018 and 2020, the impact of bankruptcy courts on the bond issuance market can be analyzed.

This paper reveals that bond issuance credit spreads increase and is more sensitive to firm size, profitability and downside risk of issuance entity after the introduction of bankruptcy courts. It also reveals a substantive increase in bond issuance quantity and a decrease in issuer credit ratings following the establishment of bankruptcy courts. In addition, the increase of credit spreads is more prominent for publicly traded bonds, those whose issuers located in provinces with lower judicial confidence, bonds issued by SOEs and bonds with stronger government guarantees. Finally, the role of bankruptcy courts is more pronounced in regions with higher marketization.

This paper relates to previous studies that investigate the impact of laws and institutions on external financing. It helps provide new evidence to this literature on how improvements of efficiency and quality in bankruptcy enforcements relate to the marketization of bond issuance. The results provide further evidence on legal institutions and bond financing.

The purpose of this paper is two fold. First, it presents the developmental stages and running modes of K12 Online Schools in China. Second, it illustrates online education practice, its current status, and the use of ICT in online schools. The experiences and lessons learned from the development of the K12 Online Schools are presented, and suggestions are summarized for the sustainable development of the schools.

This study reviews relevant literature and uses questionnaires to collect information from the Beijing No. 4 Online School, which is a representative sample of K12 Online Schools.

K12 Online Schools have experienced three stages: the initial stage, the adjustment stage, and the steady stage. There are multiple modes of running K12 Online Schools in China. The schools mainly deliver their courses through a satellite‐based TV net or the internet. The main teaching and learning strategy is still lecturing. Teacher training is critical for improving and assuring the quality of online courses.

The rapid development of ICT can propel K12 Online Schools to maturity. However, more emphasis should be put on learner support and teachers' professional development.

This article summarizes K12 Online Schools practice and their current status in China. It will help in understanding the current development of online education in China and the challenges it faces.

This study examines the impact of China’s mixed-ownership reform on the innovation of non-state-owned acquirers, with a particular focus on the impact on firms with high financing constraints, low-quality accounting information or less tangible assets.

We use a proprietary dataset of firms listed on the Shanghai and Shenzhen Stock Exchanges to investigate the impact of mixed ownership reform on non-state-owned enterprise (non-SOE) innovation. We employ regression analysis to examine the association between mixed ownership reform and firm innovation.

The study finds that non-state-owned firms can improve innovation by acquiring equity in state-owned enterprises (SOEs) under the reform. Eased financing constraints, lowered financing costs, better access to tax incentives or government subsidies, lowered agency costs, better accounting information quality and more credit loans are underlying the impact. Additionally, cross-ownership connections amongst non-SOE executives and government intervention strengthen the impact, whilst regional marketisation weakens it.

This study adds to the literature on the association between mixed ownership reform and firm innovation by focussing on the conditions under which this impact is stronger. It also sheds light on the policy implications for SOE reforms in emerging economies.

The purpose of this study is to shed light on the relationships between the different types of ownership structure and tax avoidance activities and examine the moderating effect of audit quality.

This study used secondary data from the listed companies in Amman Stock Exchange (2009–2020). To obtain additional robust findings, this study used various proxies for measuring tax avoidance (effective tax rate [ETR] and cash flow effective tax rate [CFETR]).

Relying on various proxies for tax avoidance, the results reveal that family and managerial ownership lead to exacerbating tax avoidance activities. Although institutional and board ownership have a positive impact on ETR and CFETR, which indicate that these type of ownership have a negative impact on tax avoidance. Audit quality also has a significant role in moderating the ownership structure–tax avoidance relationships. Besides, the results reveal that audit firm size is not merely symbolic words, but it contributes to reducing and restricting tax aggressiveness.

This study has policy implications related to the policymakers in creating future tax policies to minimize and avoid tax avoidance activities. Results of this study can be used to improve awareness among the various owners and to reduce the tax avoidance practices in the developing countries. It also determines a good agenda for research in the relationships between ownership identities, audit quality and tax avoidance, which also can be used to encourage and guide future studies.

This research extends the existing literature by examining both the direct and indirect influence of ownership structure on tax avoidance in Jordanian firms by including audit quality as a moderating variable. This is a pioneering and unique study examining the joint influence of the different forms of ownership on tax avoidance. To the best of the author’s knowledge, this study is the first of its kind that examines the interaction influences between the various identities of ownership and audit quality on the tax avoidance activities in the Jordanian context.

The purpose of this paper is to outline the evolution of academic and information literacy (AIL) teaching initiatives in a first-year core social work course at the University of Auckland. It traces the development of AIL teaching, support and assessment activities over a 10-year period as part of a collaborative project involving librarians, learning advisors and an academic staff member. The paper clearly outlines the challenges arising because of the rapidly evolving and complex information environment in which tertiary students find themselves, as well as the student-centred pedagogical approaches which can assist them in navigating this environment and developing resourcefulness and resilience in undertaking research.

The case study presented in this paper outlines the evolution over a 10-year period of AIL teaching and activities taken to specifically develop AIL integration for the first-year core course, Sociology for Human Services, for the degree of Bachelor of Social Work. At its core, this case study demonstrates the application of reflective practice on the part of library staff, academic staff and student learning advisors with a view to implementing AIL initiatives which not only addressed information needs for assignment completion at university but also took a holistic view of students’ lives, recognising the importance of AIL in their civic, social and work lives. Reflection involved challenging key assumptions about the teaching of AIL initiatives and what constituted success and failure; gaining a better understanding of new and developing information environments in which students currently operate; and identifying existing and emerging AIL frameworks which could best equip students to survive and flourish in these environments. The paper focuses on the drivers, challenges, successes and impact of implementing and adapting AIL activities as well as the learning design and pedagogical approaches implemented to scaffold and develop initiatives with the whole three-year degree structure in mind. Special reference is paid to the application of new and emerging AIL frameworks, including the Research Skills Development Framework (Willison and O’Regan, 2006) and the ACRL Framework for Information Literacy for Higher Education (Association of College and Research Libraries, 2015). The paper also outlines how mapping to graduate attributes, learning outcomes and core practitioner competencies can strengthen AIL and assessment activities.

Application of new and emerging frameworks of research and AIL can enhance both teaching and assessment activities in an undergraduate degree programme. This paper outlines a move away from reliance on teaching of tools and resources to a focus on mastery of threshold concepts and deeper understandings of the importance of information and academic literacy capabilities in study, work and civic life. The approach outlined here fosters the development of informed learners who are resilient and resourceful and who can easily navigate within the complex information environment in which they find themselves. This case study further demonstrates that students appreciate and recognise the value (as well as the transferability) of these capabilities to other areas of their life both at the tertiary level and post academia. In a practice-based course such as this one, the application of key frameworks and an understanding of expected practitioner competencies and graduate attributes can also help address a generally recognised research practice gap common in undergraduate practice-based courses. The paper further outlines the benefits of a collaborative approach to the integration of AIL. Such collaborative initiatives bring the fresh perspectives and deeper understanding; apart from this, they also serve as a springboard to work with other academic staff to develop AIL initiatives at different stages of a degree programme.

This paper focuses on the development of AIL skills in one social work course at the University of Auckland. The information presented here may not be relevant for other disciplines or institutions.

This paper takes both a theoretical and practical approach. Challenges in the development of AIL initiatives are clearly contextualised within relevant pedagogical and AIL theories. Practical solutions for common challenges are clearly outlined. It is hoped that the problem − solution approach outlined in this paper will benefit other information professionals and academic staff who are implementing AIL in the current tertiary environment.

Students find themselves in an increasingly complex information environment. Traditional information literacy (IL) skills may no longer meet their needs in this rapidly evolving environment. This paper outlines how application of current research frameworks, practitioner attributes and a focus on mastery of core threshold concepts can build information resilience and resourcefulness and better equip them to access, evaluate and utilise information both for their study and work and life beyond academia.

Demonstrating clear trends in how IL initiatives have developed over the past 10 years, this paper provides practical examples of how new and emerging research and threshold concept frameworks can be applied to the integration of AIL initiatives in undergraduate degree programmes.

An increasing number of Chinese enterprises are involved in cross-border mergers and acquisitions (M&As). However, few Chinese enterprises have achieved successful integration, which plays a critical role in enhancing performance. The important field of cultural integration is currently facing major challenges. To identify the reasons for these challenges, studies have analyzed why cultural integration succeeds or fails and have suggested that cultural differences between acquiring and acquired enterprises are the primary obstacles to cultural integration. However, it is unclear how success can be achieved. The paper aims to focus on cultural integration from the perspective of acculturation to describe the penetration of cultural elements in M&As.

In adopting acculturation as our theoretical lens, the authors use the case study method to answer the following research question: “how can the cultural integration of Chinese enterprises be successfully achieved?” Two typical cases are examined: Lenovo’s cultural integration with IBM’s personal computer (PC) division and Haier’s cultural integration with Sanyo home appliance. First, using the exploratory case study method, the Lenovo–IBM PC division case is analyzed. The characteristics and relationships between cultural environments, employee adoption methods and acculturation patterns are summarized to reveal a cultural integration path. Second, the Haier–Sanyo home appliance case is analyzed using the confirmative case study method to test the findings of the Lenovo–IBM PC division case.

The results indicate that it is critical to achieve a dynamic fit between cultural environments, employee adoption methods and acculturation patterns during each stage of cultural integration (exploration, experimentation, reinforcement and fixing). The three constructs of these stages reflect the following evolutionary paths: “isolate-introduce-learning-chance taking”, “detecting-icebreaking-interacting-remodeling” and “specialized sections-senior managers-managers-employees”.

These findings contribute to the development of cultural integration and acculturation theories and serve as a reference for Chinese enterprises wishing to implement cultural integration strategies.

Based on the resource-based view and dynamic capabilities theory, this study aims to examine the complementarity between market orientations and launch proficiency as a driver of new product performance.

In this research, an on-site survey of Iranian, research and development- intensive, manufacturing firms was carried out to examine the proposed hypotheses. Based on the 179 workable survey responses, a covariance-based structural equation modeling was applied to verify the proposed theoretical model.

The empirical findings reveal that the effects of market orientation or launch proficiency alone are not significant while the complementarity between them significantly influences new product performance. These research outcomes suggest that this complementarity leads to a bidirectional co-specialization relationship in firms, promoting both market intelligence generation processes and product-launch capabilities, and therefore resulting in superior new product performance.

The current characterization of the resource-based theory signifies that strategic resources merely have potential value and actualizing this value needs complementary organizational capabilities. Furthermore, the literature notably lacks empirical findings supporting these complementarities. Therefore, the findings concerning the bidirectional co-specialization between market orientation and launch proficiency not only provide empirical support for the dynamic capabilities theory but also address recent research calls to identify and calibrate the importance of dynamic capabilities for leveraging market orientation on new product performance.
