Abstract
Purpose
The purpose of this paper is to examine the criteria of uniqueness of the equilibrium point and the new stability criteria for stability of the equilibrium point. The new stability condition is dependent on the size of delays.
Design/methodology/approach
The global asymptotic stability of a class of delayed bi‐directional associative memory (BAM) neural networks is studied. Some new sufficient conditions are presented for the unique equilibrium point and the global stability of BAM neural networks with time delays by constructing Lyapunov functions and using the linear matrix inequality. A numerical example is presented to illustrate the effectiveness of the theoretical results.
Findings
Based on the mathematical method and matrixes inequality skill, some criteria are obtained which contain the unique equilibrium point and the global stability of BAM neural networks.
Research limitations/implications
The paper proposes the new Lyapunov function and new skill to compose matrixes inequality.
Practical implications
A very useful method for BAM neural network to judge the uniqueness of the equilibrium point and stability.
Originality/value
The new mathematical model is proposed about the production process, and the new control method is used in the temperature system for a double layers welded pipe in welding process.

Abstract
Purpose
The purpose of this paper is to investigate the conditions under which working with an incumbent downstream competitor could be a beneficial strategy for upstream firms as the case of the relationship between banks and third-party payment providers.
Design/methodology/approach
Using a game model, this study considers a market with two upstream firms (banks) and two downstream firms (third-party payment providers). One downstream firm is an incumbent that poses a competitive threat to the upstream market, and the other downstream firm does not.
Findings
The results show that the optimal decision for banks depends on the number of loyal users the incumbent third-party payment providers and banks have. When the bank has more loyal users than the competitive third-party provider to a certain level, it would terminate cooperation with the provider; otherwise, the bank would maintain cooperation. This is true whether the duopoly banks are symmetrical or asymmetrical.
Originality/value
This study makes contribution to the theory of co-opetition lies in the fact that it examines a special case of competition and cooperation between vertical enterprises in the bank context. This study investigates how the upstream firms do when threatened by a downstream firm while the upstream firms have other options. This study also contributes to bank marketing theory through providing explanations for some of the incomprehensible cooperation in China's payment market, which is characterized by consumer loyalty. This study extends previous new-entry competition for banks by differentiating between incumbent and new-entry downstream firms.

Abstract
Purpose
This paper aims to investigate the extent to which the management control systems (MCS) adoption in corporate social responsibility (CSR) integration into business strategy has an impact on companies’ performance.
Design/methodology/approach
Using a sample of 435 Indonesian manufacturing companies, partial least squares structural equation modelling was used to investigate the impact of CSR strategic integration on companies’ performance based on the contingency and stakeholder theories.
Findings
The findings reveal CSR strategic integration has a positive and significant impact on companies’ performance, including employee, operating and financial performance and the company size can positively moderate the impact of this integration on both its operating and financial performance.
Practical implications
The findings can encourage managers to adopt MCS by undertaking CSR at the strategic level, resulting in superior performance, both socially and financially.
Social implications
Employee performance and operating performance can significantly mediate the effect of strategic integration on financial performance.
Originality/value
The paper suggests that adopting MCS through CSR strategic integration could improve company performance socially and financially. This is the very first study on this issue from an Indonesian perspective.

Abstract
Purpose
Corporations, as key contributors of greenhouse gas emissions, have been increasingly scrutinized by governments and stakeholders. Corporations have been asked to disclose their carbon-related information. This study investigates public corporate carbon disclosure, an imperative communication channel between firms.
Design/methodology/approach
This study uses generalized estimation equation models with a longitudinal panel data of 311 listed firms in the China A-share stock index from 2010 to 2020. This study collected firm-level data from the Carbon Disclosure Project survey, the China Stock Market and Accounting Research, and the National Economic Research Institute of China. Stata was used as the primary statistic software in empirical analyses.
Findings
This study finds that compared to state-owned enterprises (SOEs), private firms are more willing to disclose carbon information under legitimate environmental pressure, and firms in highly distorted factor-markets are reluctant to disclose carbon information. This study finds that factor-distortion markets further moderate ownership and lead private firms in highly distorted factor-markets to behave like SOEs by significantly reducing their carbon disclosures.
Originality/value
This study intends to contribute to the corporate carbon disclosure literature by adding important institutional determinants to the conversation in the context of China.

Abstract
Purpose
The purpose of this paper is to examine the Chinese media’s performance on reporting the issue of waste incineration power plants. The authors analyze the role of media in supervising relevant agencies and meeting the public need for related information.
Design/methodology/approach
This paper provides a content analysis of media reports toward waste incineration projects that follow the anti-incinerator event that occurred in Panyu district of Guangzhou city in 2009. The sample of this paper is based on 469 news reports that were released on the state-level search engine “ChinaSo.com” from January 2010 to June 2016.
Findings
Chinese media did not continue to focus on waste incineration issues after the anti-incinerator event in the Panyu district and there were only a few news reports about this topic. News reports of the information disclosure category accounts for the largest proportion but lack a depth of explanation. The proportion of news reports of media supervision and popular science information categories is relatively small.
Research limitations/implications
This paper is a pilot study of the media’s reporting characteristics on waste incineration issues. There are some shortcomings in terms of sample selection and analysis, more in-depth assessment will be implemented and improved upon the future research. This study highlights the importance of media reports before or after relevant events in examining the media’s social function. Besides, this study provides a new analytical idea for assessing the functions of the media on social public issues through media reports and the conclusions of this study have certain practical significance for the media to improve report behaviors.
Originality/value
This paper selects media reports on waste incineration power plant after the anti-incinerator event in Panyu district as media industry could pay much attention to relevant topics before the beginning of conflict events and continue tracking reports even after the events subside. This paper points out that Chinese media might increase sustained attention to waste incineration issues, strengthen the depth of interpretation, increase the supervision of relevant agencies, and enhance the relevance of the news reports to the public.

In structural health monitoring, localization of multiple slight damage without baseline data is significant and difficult. The purpose of this paper is to discuss these issues.
Abstract
Purpose
In structural health monitoring, localization of multiple slight damage without baseline data is significant and difficult. The purpose of this paper is to discuss these issues.
Design/methodology/approach
Damage in the structure causes singularities of displacement modes, which in turn reveals damage. Methods based on the displacement modes may fail to accurately locate the slight damage because the slight damage in engineering structure results in a relatively small variation of the displacement modes. In comparison with the displacement modes, the strain modes are more sensitive to the slight damage because the strain is the derivative of the displacement. As a result, the slight variation in displacement data will be magnified by the derivative, leading to a significant variation of the strain modes. A novel method based on strain modes is proposed for the purpose of accurately locating the multiple slight damage.
Findings
In the two bay beam and steel fixed-fixed beams, the numerical simulations and the experimental cases, respectively, illustrate that the proposed method can achieve more accurate localization in comparison with the one based on the displacement modes.
Originality/value
The paper offers a practical approach for more accurate localization of multiple slight damage without baseline data. And the robustness to measurement noise of the proposed method is evaluated for increasing levels of artificially added white Gaussian noise until its limit is reached, defining its range of practical applicability.

Abstract
Purpose
This paper aims to successfully synthesize three-dimensional spindle-like Au functionalized Co3O4-ZnO nanocomposites; characterize the structure, morphology and surface chemical properties of the products; study the effect of Au NPs doping concentration, operating temperature different gas to, sensing properties; and introduce an attractive gas sensor for acetone detection.
Design/methodology/approach
Au NPs functionalized Co3O4-ZnO nanocomposite was prepared by coprecipitation and impregnation methods; the structure and surface chemical property of the products were characterized by XRD, SEM, TEM, UV-Vis, BET and XPS. The sensing ability of Au@Co3O4-ZnO for acetone and mechanism was analyzed systematically.
Findings
The results of gas sensing tests show that the unique component structure, Schottky junction and catalytic effect of Au functionalization make it have low operating temperature, excellent selectivity, high response (10 ppm, 56) and rapid response recovery time.
Research limitations/implications
All the characterization and test data of the prepared materials are provided in this paper and reveals the gas sensing mechanism of the gas sensor.
Practical implications
The detection limit is 2.92–100 ppb acetone. It is promising to be applied in low-power, micro detection and miniature acetone gas sensors.
Social implications
The gas sensor prepared has a lower working temperature and low detection limit, so it has promising application prospects in low-concentration acetone detection and early warning.
Originality/value
The unique component structure, Schottky junction and catalytic effect of Au functionalization Co3O4-ZnO make it have low operating temperature, excellent selectivity and rapid response recovery time.

Abstract
Purpose
The new programming period of 2021–2027 of the European Union (EU) Common Agricultural Policy requires reconsidering the policy measures. In the new period, the European Commission is to allow each member state (MS) developing eco-schemes to support and/or incentivise farmers to observe agricultural practices beneficial for the climate and the environment beyond their mandatory requirements. The purpose of this paper is to compare the performance of organic and conventional family farms.
Design/methodology/approach
Organic farming under the organic farming measure of the Rural Development Programme is one of the most widely applied sustainable farming practices in the EU as well as in Lithuania. By assessing the ex post economic impact of the organic farming measure on farm performance indicators, the authors seek to reveal possibilities and obstacles for the implementation of sustainable farming practices. A counterfactual ex post impact assessment method – propensity score matching (PSM) analysis – was used to evaluate ex post economic impact of the organic farming measure on the performance of farming indicators.
Findings
The application of the PSM allowed assessing both the effectiveness of the implemented measure and possibilities for applying this measure in the future. The research has revealed that organic farming is less profitable and the gap between farm income in organic and conventional farms has increased during the period of 2007–2013.
Originality/value
The most comprehensive economic information about the farm activities from the Farm Accountancy Data Network (FADN) was used for the ex post economic impact evaluation of the organic farming measure in Lithuania. The matched groups of Lithuanian family farms (organic and conventional) were compared. The results of the research provide a new knowledge about the effectiveness of the organic farming measure in Lithuania and suggest the ways of their improvement in the future. The results can also be generalised to other countries with similar agricultural structure.

Abstract
Purpose
The purpose of this paper is to discuss the influence of different aspects of top management team (TMT) functional background on short-term performance, long-term performance, innovation performance and oversea performance separately. This research aims to verify whether the social categorization theory and information and decision-making theory are applicable in listed companies of China’s information technology (IT) industry so as to provide key theoretical references for TMT enhancement ad corporate performance improvement.
Design/methodology/approach
This paper takes A-share listed companies in Shanghai Stock Exchange and Shenzhen Stock Exchange as its study subjects, and it chooses the data from 2004 to 2010 in all of the 105 companies in IT industry in terms of the classification of Wind Database. The stepwise multiple regressions were run utilizing the regression program in Statistical Product and Service Solutions (SPSS).
Findings
The research results show that the social categorization theory can better explain TMT’s influence on corporate performance. TMT functional heterogeneity does not contribute to improving corporate performance and shows significant negative influence on short-term performance and innovation performance in particular. Among the three basic functional backgrounds, TMTs dominated by “throughput” backgrounds show significant positive influence on short-term performance, long-term performance, innovation performance and overseas performance, and the influence turns out to be the largest among these three backgrounds. In terms of the three special professional experiences, top executives with overseas backgrounds have significant positive influence on all of short-term, long-term, innovation and overseas performances. Externally hired executives, however, would impede corporate innovation development, while those with government background would increase corporate overseas performance.
Originality/value
This paper analyzes the relationship between TMT functional background and corporate performance in a comprehensive way for the first time and then takes the lead in considering the dynamics and complexity of corporate performance as well as discussing the influence of TMT functional background on four corporate performances. This study not only supports the effect that the social categorization theory has on TMTs but also offers some inspirations on the development of China’s IT companies.
