Implementing and evaluating an automatic centroid moment tensor procedure for the Indonesia region and surrounding areas

The purpose of this research was to suggest an applicable procedure for computing the centroid moment tensor(CMT)automatically and in real time from earthquakes that occur in Indonesia and the surrounding areas.Gisola software was used to estimate the CMT solution by selecting the velocity model that best suited the local and regional geological conditions in Indonesia and the surrounding areas.The data used in this study were earthquakes with magnitudes of 5.4 to 8.0.High-quality,real-time broadband seismographic data were provided by the International Federation of Digital Seismograph Networks Web Services(FDSNWS)and the European Integrated Data Archive(EIDA)Federation in Indonesia and the surrounding areas.Furthermore,the inversion process and filter adjustment were carried out on the seismographic data to obtain good CMT solutions.The CMT solutions from Gisola provided good-quality solutions,in which all earthquake data had A-level quality(high quality,with good variant reduction).The Gisola CMT solution was justified with the Global CMT(GCMT)solution by using the Kagan angle value,with an average of approximately 11.2°.This result suggested that the CMT solution generated from Gisola was trustworthy and reliable.The Gisola CMT solution was typically available within approximately 15 minutes after an earthquake occurred.Once it met the quality requirement,it was automatically published on the internet.The catalog of local and regional earthquake records obtained through this technology holds great promise for improving the current understanding of regional seismic activity and ongoing tectonic processes.The accurate and real-time CMT solution generated by implementing the Gisola algorithm consisted of moment tensors and moment magnitudes,which provided invaluable insights into earthquakes occurring in Indonesia and the surrounding areas.

Balancing Openness and Protection:Homogenization of Regulatory Laws in Digital Service Trade

Digital service trade has emerged as a pivotal engine for global economic transformation and development.However,the implementation of differentiated regulatory measures for trade in digital services among economies has led to increasingly frequent trade disputes.This paper constructs a regulatory homogeneity network for digital service trade in 60 major economies,and systematically evaluates the structural characteristics of the network and the regulatory homogeneity among economies from 2014 to 2021.Furthermore,this paper empirically examines the impact of the partnership characteristics of regulatory homogenization in the network of major economies on their exports.The analysis of the network structure shows that major economies are more inclined to optimize and simplify existing trade partnerships,and are moving towards more diversified restrictive measures in the regulatory model of digital services trade,which has led to the rise of trade protectionism.The empirical text results show that expanding and deepening the regulatory homogeneous partnership of trade in digital services promotes the export of digital services in major economies.This promotion effect is mainly achieved by reducing the cost of digital service trade and enhancing business trust.In addition,the export promotion effect of developing regulatory homogenization partnerships is better than that of increasing the openness of digital service trade,and the homogenization of policies between openness and protection is more important.This paper provides important implications for coordinating the openness and security of digital services trade:China should actively cooperate with multilateral and bilateral digital service trade partners to jointly build a homogeneous environment for regulatory regulations.In particular,it is necessary to deepen the regulatory homogeneity partnership with Asian and developing economies to expand the infl uence of the“China model”in the global regulation of digital services trade.

Is money going digital? An alternative perspective on the current hype

Current financial discourse suggests the imminence of a cashless society,a concept that arose from the global popularization of digital financial services and the development of technologies with the potential for application in financial markets.However,claims about the impending obsolescence of paper money are neither disruptive nor a novelty.Instead,this paper argues that the conversion of money from paper to bits has been a gradual,adaptive process,and that money is already digital.Moreover,in this paper we propose that the statuses of electronic money(e-money)and banknotes have switched in the view of monetary authorities.

General review of National Digital Library development in the National Library of China

As an important part of National Digital Library(NDL),the National Digital Library Project(NDLP),which was launched in 2005,has attracted wide attention of the society in general.This paper introduces the general situation of the project from the following aspects,namely,the characteristics,objectives and contents.It also expounds on the basic ideas and the overall structure of the project and gives an introduction to the design of its basic platform,its application platform,its business management system and its standardization control system.In this paper,the digital resources construction and service delivery of the National Library of China(NLC)are introduced to cover both its present operation as well as those in conjunction with the opening of its new library building during its second-phase of library development.Finally,the most important and difficult point in the construction of the National Digital Library Project is analyzed from the following four perspectives:1)The long-term preservation of digital resources;2)the construction of knowledge organization system;3)the organic integration of the digital library and the traditional library;and 4)the risk of project management and system integration.

The Negative Influence of Chinese L1 on English L2 Writing

L1 is,generally,believed to affect the acquisition of second language negatively.Because there is likely to be a negative transfer form L1 to L2,when the learner lacks sufficient knowledge for communicating his or her ideas in L2 and then draw upon the L1.The transfer includes both positive and negative transfer.However,the role of L1 is more often viewed as negative,causing negative transfer that results in a variety of errors.Generally,English and Chinese do not have many of the shared syntactical features.Hence the syntactic transfer is predictable when using the L2.This may lead to such errors as those in the noun phrase,in the verb phrase and various omissions.This paper analyses those errors in English writing,which represent the negative syntactic transfer from Chinese to English.Moreover,it discusses in details the particular causes for that transfer and propose improving the awareness of the syntactic distinction between these two languages in Chinese students.

Digital Social Connectedness as a Lifeline for Older People: Use and Non-use of VinclesBCN During the Pandemic

This article presents the results of a study that evaluated VinclesBCN during COVID-19. This digital-based public social service aims to prevent loneliness and isolation in +65-year-old adults living in Barcelona. Through service user(N = 12) and professional(N = 6) interviews and a questionnaire with service users(N = 255), we demonstrate the pivotal role of digital connectedness in transforming VinclesBCN into a lifeline during the pandemic. The analysis revealed the importance of sociability, social support, and, especially, entertainment in coping with pandemic fatigue and facilitating social connectivity and support among users. Users engaged in activities such as sharing images, songs, memes, and daily greetings to provide proximity, sociability, and care among users, whether they belonged to preexisting groups or were newly introduced to the platform. It also facilitated the identification of individuals who needed companionship, comfort, or more specialized support. The findings emphasize the significance of entertainment as a resilience-building strategy during times of uncertainty. Despite the positive impact, not all users equally used the platform. Non-use was strongly associated with being a woman, having a low educational level, having preexisting social relationships, less time of enrolment in the platform, as well as a high perception of loneliness, poor self-reported health, and low mood. The article underscores the need for further research into older adults' digital engagement during crises, its role in building resilience, and advocating for inclusive digital interventions that take into account diverse older adults' needs and experiences in crisis contexts.
