    Abstract In order to improve the quality and efficiency of music teaching, we try to automate the teaching of music notation. With the addition of computer vision technology and note recognition algorithms, we improve the generative adversarial network to enhance the recognition accuracy and efficiency of music short scores. We adopt an embedded matching structure based on adversarial neural networks, starting from generators and discriminators, respectively, to unify generators and discriminators from the note input side. Each network layer is then laid out according to a cascade structure to preserve the different layers of note features in each convolutional layer. Residual blocks are then inserted in some network layers to break the symmetry of the network structure and enhance the ability of the adversarial network to acquire note features. To verify the efficiency of our method, we select monophonic spectrum, polyphonic spectrum, and miscellaneous spectrum datasets for validation. The experimental results demonstrate that our method has the best recognition accuracy in the monophonic spectrum and the miscellaneous spectrum, which is better than the machine learning method. In the recognition efficiency of note detail information, our method is more efficient in recognition and outperforms other deep learning methods.

    Abstract In the last two years, due to the pandemic and restrictive measures, the dependence of music creators and artists on the Internet, where they could promote their work, organize live streaming concerts, and talk to the public, has increased and expanded even more and seeks higher revenue from digital music platforms. An important issue that arises from the above statement is protecting the authors’ copyright regarding the uses and sharing in the digital services of their works with protected content. Although circulated in digital information, the protected content is not information but a product of ethical and commercial value. While it has an intangible owner and it owes its existence to the creative idea of its creator, it is not an idea. The imposition of legal and commercial conditions on its movement cannot be associated with any restrictions on the free movement of information, as it is not related to them. In general, the unauthorized exchange of digital music files via peer-to-peer violates copyright law. The exchange of files is unauthorized, as it does not have the relevant permission from the creators and beneficiaries and is therefore illegal. With this in mind, this paper proposes a highly effective way of protecting the copyright of music technology, which is based on the widespread use of artificial intelligence, blockchain, and cryptography technologies. Specifically, an advanced blockchain model based on Hyperledger Fabric is introduced, which, however, uses Quantum Homomorphic Encryption and Quantum Zero-Knowledge Arguments. Music files are implemented as Nonfungible Tokens (NFTs), which activate smart contracts. Finally, an advanced collaborative filtering algorithm provides recommendations for effectiveness in securing the copyrights of music industry creators. A specialized scenario was built to model the proposed system to verify the degree of protection on music intellectual property in developing a security simulation with an innovative consensus-based zero knowledge and the quantum ...

    Abstract The purpose was to examine the relationship between intergenerational support, perceived health and subjective wellbeing (SWB) of the elderly’ s in China, and what role perceived health played in this study. Based on data from Chinese General Social Survey (CGSS) in 2017 ( N = 1,373), regression analysis was employed to test the mediation effects by software STATA17.0 and Macro PROCESS3.50. The regression results showed that intergenerational support including intergenerational support received and provided had a positive relationship with the elderly’s SWB. And perceived health was positively related to the elderly’s SWB in all models. Providing intergenerational support had a positive impact on the perceived health of elders, but receiving intergenerational support cannot significantly influence it. And the mediating role of perceived health was played in the relationship between the providing intergenerational support and the elderly’s SWB, rather than between the receiving intergenerational support and the elderly’s SWB. Although some limitations were there, the findings contributed to addressing theoretical gaps and giving references for the improvement of policies. Attention should be paid to the effect of intergenerational support on the elderly’s SWB.

    Abstract Abstract It is of great significance to carefully evaluate the actual impact of macro-policy formulation on promoting micro-enterprise innovation and implementing innovation-driven strategies. This study utilizes data from Chinese listed companies between 2012 and 2019 and takes the implementation of urban agglomeration policies as a natural experiment. By employing the multi-period differential method, the driving mechanism of urban agglomeration policies on enterprise innovation is investigated. The results show that: (1) Urban agglomeration policies effectively promote the enhancement of regional enterprises’ innovation capability. (2) Urban agglomeration policies reduce enterprise transaction costs through integration effects, mitigate the influence of geographical distance through spillover effects, and stimulate enterprise innovation. (3) Urban agglomeration policies have a regulatory effect on the siphon and spillover mechanism formed by the central city, thereby driving the innovation and development of peripheral micro-enterprises. (4) Further research from the perspectives of enterprises, industries, and locations reveals that the macro, medium, and micro effects of urban agglomeration policies differ, leading to heterogeneity in enterprise innovation responses. Therefore, it is necessary to continue promoting policy planning for urban agglomerations, enhance the coordination of urban policies within urban agglomerations, adjust the influence of the self-mechanism of urban agglomerations, and foster the formation of a multi-center innovation structure and network within urban agglomerations.

    Abstract Cross-border pharmaceutical value chains are expanding their presence in international production, including in the highly profitable RD link. Leading pharmaceutical companies, known as Big Pharma, are establishing contract relationships with research organizations in many countries around the world, including emerging economies where China plays a very significant role. The purpose of this study is to assess the placement and location of Chinese contract research organizations in the RD links of the international pharmaceutical chain. As a result of the study, the authors came to the following conclusions. The development of the Chinese market can be dated to the beginning of the 2000s, when outsourcing firms for large international pharmaceutical companies began to be created. The Chinese market for contract research organizations has developed at a faster rate compared to the world market. As the key explanations for the rapid development of the Chinese market, the authors highlight the strong state support of the Chinese government, the improvement in the quality of research services provided by Chinese companies, as well as the lower price of these services compared to competitors. Market development relies primarily on the close ties of Chinese contract research organizations with Big Pharma companies. Demand from local Chinese pharmaceutical companies and from foreign affiliates of small and medium-sized of pharmaceutical companies located in China plays an increasing role in stimulating the market for contract research organizations. The rapid development of the Chinese market for contract research organizations has been accompanied by its consolidation and concentration, as well as monopolization in some market subsectors. Market consolidation was also supported by the accelerated pace of MA in pharmaceutical RD amid the pandemic.

    Abstract Summary: N6-methylation of adenosine (m6A) is the most abundant internal mRNA modification and is an important post-transcriptional regulator of gene expression. Here, we describe a protocol for methylated RNA immunoprecipitation sequencing (MeRIP-Seq) to detect and quantify m6A modifications in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA. The protocol is optimized for low viral RNA levels and is readily adaptable for other applications.For complete details on the use and execution of this protocol, please refer to Li et al. (2021).

    Abstract Regarding the fact that smallholder farmers form the main part of agriculture, actively guiding smallholder farmers to continually adopt the farmland quality improvement practice in their agricultural production process is considered as the critical path to improve farmland sustainability for the agricultural sector in China especially smallholder farmers planting economic crops, such as tea, that have long relied on heavy inputs of chemical fertilizers that seriously undermine the quality of farmland. However, the state efforts towards the promotion of farmers’ adoption of farmland quality improvement practices for years have not obtained remarkable results. In this context, based on expectation confirmation theory and conservation of resources theory, the study classified farmers’ perceived stress towards continual adoption of farmland quality improvement practice into three categories: stress from uselessness perception, difficulty perception, and in-adaptability perception. A structural equation model was utilized to explore the impact of perceived stress on farmers’ continual adoption of the practice in a sample of 494 tea farmers from Qinba Mountain Area in China. Additionally, the mediating effect of self-efficacy and moderating effect of social support are discussed theoretically and empirically in the paper. The research findings show that the stress from in-adaptability perception has the strongest inhibitory effect of the three on farmers’ continual behavior while the stress from difficulty perception is the weakest. Further, the mediating effect of self-efficacy in the relationship between perceived stress and farmers’ continual adoption behaviors was confirmed. Additionally, the study indicated that social support can buffer the negative impact of perceived stress from uselessness perception and difficulty perception on farmers‘ continual adoption behaviors. Therefore, fully considering farmers’ perceived stress, providing farmers with support in a targeted manner, would strengthen the coordination ...

    Abstract Under different carbon regulatory policies, corporate social responsibility (CSR) activities will have different impacts on the environmental benefits of the supply chain and corporate carbon emission reduction decisions. In this study, we examine a dual-channel closed-loop supply chain consisting of a single manufacturer selling re-products generated from waste products and a single retailer selling new products and consider two settings: enforcing a carbon tax policy or enforcing a subsidy policy. Under each setting, we put CSR into account, construct two models for the retailer to implement or not implement CSR activities, and analyze the decisions obtained under optimal solutions. Through numerical simulation and comparative research, we observe that the carbon tax policy applies to the supply chain where CSR activities are implemented, while the subsidy policy applies to the supply chain where CSR activities are not implemented. Reasonable selection of CSR implementation methods with low-cost coefficients by the retailer is conducive to eliminating profit conflicts among supply chain members. The government should fully consider the decision-making thresholds of supply chain members to ensure the maximum effectiveness of the policy.

    Abstract Whether the place-based industrial policy promotes regional economic growth is a hot issue in the field of regional industrial economic practice. As a major national strategy in China, the Beijing-Tianjin-Hebei industrial coordinated development policy has been implemented more than 8 years. Verifying its effect on regional economic growth and revealing the policy action path will help to further optimize the policy implementation process through feedback. In this paper, the policy effect and its differentiation are empirically studied from 'quality' and 'quantity' respectively by establishing a growth model using the Dual Differences method. The results show that the Beijing-Tianjin-Hebei industrial coordinated development policy improves total factor productivity by 2.26% in terms of 'quality', and reduces GDP growth rate by 4.65% in terms of 'quantity'. For the different region, the GDP growth rate increased by 1.28%, while total factor productivity decreased by 2.63% in Beijing, the GDP growth rate decreased by 3.17% and total factor productivity increased by 0.87% in Tianjin, and the GDP growth rate increased by 2.56% and total factor productivity increased by 1.58% in Hebei. The policy is mainly realized by fixed asset investment, capital deepening degree and enterprise scale expansion, while the effect of labor input, R&D investment and enterprise number is not significant. The policy is to give full play to the driving role of fixed asset investment such as "new infrastructure", increase investment in labor and research and development in the region, strengthen the construction of a competitive market environment, and stabilize the 'quality' and 'quantity' to further release policy dividends.
