Research on the Information Tracing Model for Cross-border E-commerce Products based on Blockchain

Information asymmetry, information island, high regulatory cost, etc., emerge from the fast development of cross-border e-commerce in China, for which the blockchain, with its capabilities in information sharing, information traceability, smart contract, and so on, can play an effective role in product information tracing. Based on blockchain, this paper builds the product information tracing model using information chains of two different degrees of openness. The model includes the three major bodies of cross-border e-commerce—the supply chain alliance, the consumers and the regulatory departments, so as to produce information tracing, ensure information authenticity and integrity, and be applicable to all kinds of e-commerce platforms.

An ancient coronavirus-like epidemic drove adaptation in East Asians from 25,000 to 5,000 years ago

SummaryThe current SARS-CoV-2 pandemic has emphasized the vulnerability of human populations to novel viral pressures, despite the vast array of epidemiological and biomedical tools now available. Notably, modern human genomes contain evolutionary information tracing back tens of thousands of years, which may help identify the viruses that have impacted our ancestors – pointing to which viruses have future pandemic potential. Here, we apply evolutionary analyses to human genomic datasets to recover selection events involving tens of human genes that interact with coronaviruses, including SARS-CoV-2, that started 25,000 years ago. These adaptive events were limited to ancestral East Asian populations, the geographical origin of several modern coronavirus epidemics. An arms race with an ancient corona-like virus may thus have taken place in ancestral East Asian populations. By learning more about our ancient viral foes, our study highlights the promise of evolutionary information to combat the pandemics of the future.

Deciphering Fake News: Navigating Today’s News Standards

Following the 2016 presidential election, the pervasiveness of fake news came into the national spotlight. With an increased focus on media literacy and the need to end the spread of false information, tracing the abilities of individuals to spot fake news through a series of interviews was relevant. Several research questions were used for guidance: What are the common understandings or misunderstandings of fake news and its perpetuation? What are the characteristics of individuals who are more apt to recognize fake news? Does an individual’s level of political activism or civic engagement affect their ability to recognize fake news? It was hypothesized that the interviewees’ understanding of fake news and accuracy in distinguishing real and fake news would be dependent on their news-reading habits. Interview conduction confirmed the accuracy of this hypothesis. Furthermore, those who engaged with news more often and more widely are more likely to accurately discern between what is true and false. Questions remain as to whether or not those who had more experience with political activism and civic engagement, or with educational backgrounds relating to those areas, are better at making this differentiation. The results of this study reinforce the vitality of being media literate and possessing a consistent awareness of current events.

SIKAP MAHASISWA TERHADAP FASILITAS DAN PELAYANAN PERPUSTAKAAN UNIVERSITAS ATMA JAYA YOGYAKARTA

The objectives of the study on attitude are: (l) to investigate the attitude of the students toward thefacilities and theservices of Atma Jaya Yogtakarta University library and (2) to uncover the difference in the attitude of the students majoring in exact disciplines and those majoring in non-exact ones toward the facilities and the services of the Atma Jaya Yogyakarta University library. The study is conducted in the Atma Jaya Yogyakarta University with 200 samples as respondents. They consist of 100 degree students majoring in exact disciplines and 100 degree students majoring in nonexact disciplines. The analysis of the study is quantitative-descriptively conducted and the method employed is of applied statistics one. Subsequently, the analysis and the hypothesis are examined using one-way ANOVA.The result of the study shows that: (1) the attitude of the students toward the facilities of the Atma Jaya Yogtakarta University library tends to be both positive and negative in general. There are 4.5% of the 200 respondents having negative attitude, 4 t .5% having the tendency of negative attitude, 49.5% having the tendency of positive attitude; and (2) the attitude of the students toward the service of the Atma Jaya yogtakarta University library tends to be positive in general. There are 2% of the 200 respondents having negative attitude, 18% having the tendency of negative attitude, 60% having the tendency of positive attitude, 19.5% having positive attitude and 0.5oh having very positive attitude; (3) there is a significant dffirence in attitude between the students majoring in exact disciplines and those majoring in non-exact disciplines toward the facilities and the services of the Atma Jaya Yogtakarta University library. The student majoring in non-exact disciplines have more positive attitude thqn those majoring in exact disciplines; and (4) there is a significant diference in the attitude between the students majoring in exact disciplines and those majoring in non-exact disciplines. The difference in attitude is found especially in the services of information tracing and copying. The attitude of the students majoring in exact disciplines is more positives than those majoring in non-exact disciplines toward the two services.

Carry out the Green Brand Construction: A Case Study

It is of great significance to carry out the green brand construction for enterprise’s sustainable development. Shanghai WANSHIFA, an industrial head company in Shanghai, constructs green brand successfully through clearing brand strategy of green company, implementing the third party certification, special trademark registration, improving the product traceability and setting different brand sales paths and strategies according to the characteristics of brands. The practice shows that it is necessary for the green product brand to locate the green brand strategy correctly. The application of a unique registered trademark of third-party certification is necessary for the enterprise. The success of green brand needs effectively marketing strategy and network. The green product information tracing system is the trend for the green brand construction.

Framework of RFID-Based Infrastructure Project Quality Management Expert System

This paper presents a real time information tracing and monitoring expert system for the infrastructure project quality management with radio frequency identification (RFID) technology. This paper purposes to research the improvement of the real time information tracing method and the quality management in the infrastructure project. The paper studies and analyzes the advantages and issues of RFID technology and structures a RFID tracing system. Based on a value-focus-process (VFP) model of the project, a quality expert management system is built with the composition of RFID systems, VFP expert system and project management system. The VFP expert system inspects project quality by tracing the activities of the materials and members objectives in the project, and analyzes the information to determine the causes of abnormal and how to guarantee the quality. The VFP expert system also provides security schemes for the project to avoid risks. By utilizing RFID tracing technology, the project management system may be more effectively and sensitive with accidents than the traditional one. The paper finds that the quality management workflow in infrastructure project can be more visible and controllable with an RFID-based VFP expert system.
