Its application has brought much convenience to people's study, work, and life, and hassimultaneously caused some phenomena against public order and good deeds. From the perspective ofepistemology, they are the consequences of human's cognitive fragmentation, superficiality, and human'suncontrolled self-discipline ability. In order to fundamentally reduce or avoid the occurrence of these socialproblems caused by live video streaming, the key points might be not only supervising and guiding live videostreaming in time, but also improving the participants', especially juveniles' abilities of rational judgment andself-discipline through providing them with specific publicity and education. In this aspect, the thoughts of"observing things by Heart" and "emotion dominated by rationality" in traditional Chinese culture can be fully usedto strengthen the assessment and governance of phenomena in live video streaming.展开更多

Separating the consulting services from the auditing services becomes a general trend at present. It is indispensable to determine the boundary of auditing and consulting, and simultaneously regulating the internal control within their respective fields. On the premise of transparency of financial information, the auditing service has been separated in some countries, in order to improve the credibility of accounting information. Relevant measures include measures conducted by the management officials to ensure the quality of financial report, enhancement of the responsibilities of the auditors, and the standard formulated by the government to evaluate the auditing process and auditing opinion. Statement on conceptual framework related to assurance engagement, proposed by the Japanese government (below called "statement proposed by the Japanese government for short), which verifies the credibility of financial information, is an example of the above-mentioned trend. Compared with Japan, China has different regulations and laws in relation to the assurance engagement.展开更多

A national library law is currently being enacted while several local library legislations have already seen fruitful results. In the enactment of 'Regulations for the Protection of Information Network Dissemination Rights', the library professional participated for the first time in enacting a national copyright law, which led to unprecedented flourishing of library activities and copyright studies. The promulgation of another legal framework,'Government Information Disclosure Regulations' further advanced the research on related issues and pushed forward government information services in public libraries in the same way. A new landmark for library legislation in recent years is the promulgation of'Guidelines for Land Utilization for Public Library Construction' and 'Public Library Construction Standards', while the framing of 'Rules of Professional Ethics for Librarians in China(On trial)' and the 'Library Service Manifesto' give indication that a framework of self-disciplinary measures of library professionals is established.展开更多
