Method of interaction item decentralization

1. According to Hou Jietai: the so-called centralization refers to subtracting the mean value of a variable from its expected value. For sample data, each observation value of a variable is subtracted from the sample average value of the variable, and the transformed variable is centralized
for your question, subtract the mean from each measurement.

2. Decentralization is a phenomenon or structure, which can only appear in a system with many users or nodes, and each user can connect and influence other nodes. Generally speaking, everyone is the center, and everyone can connect and influence other nodes. This flat, open-source and equal phenomenon or structure is called "decentralization"< Br > at the same time, "decentralization" is one of the typical features of blockchain, which uses distributed storage and computing power. The rights and obligations of the whole network nodes are the same, and the data in the system is jointly maintained by the whole network nodes, so that the blockchain no longer relies on the central processing node to realize the distributed storage, recording and updating of data. Each blockchain follows a unified rule, which is based on a cryptographic algorithm rather than a credit certificate, and the data update process needs to be approved by the user, so that the blockchain does not need the endorsement of intermediaries and trust institutions< The characteristics of br> de centralization:
centralization is first reflected in diversification. In the Internet world, there are no more than several portals has the final say. Various websites have begun to voice their own voice, express different choices and different hobbies, and these websites are distributed in every corner of the Internet world. Br > decentralisation is followed by the centralization of people, and decentralisation of content has become a trend, and people have become the key force to determine the survival of websites. It's a great change to build a website with indivials who lack interaction to gather talents and contribute their wisdom in the form of a circle. That is user-oriented, humanized< < br > decentralized content: < br > decentralization is the form of social relationship and content generation formed in the development of the Internet, which is a new network content proction process relative to "centralization"< Br > compared with the early Internet (Web1.0) era, today's Web (Web2.0) content is no longer proced by professional websites or specific groups of people, but is created by all Internet users with equal rights. Anyone can express their views or create original content on the Internet to proce information together< Br > with the diversification of network service forms, the decentralized network model is becoming clearer and more possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together< After that, with the emergence of more simple and easy-to-use decentralized network services, the characteristics of Web2.0 became more and more obvious. For example, the birth of services more suitable for ordinary Internet users, such as twitter and Facebook, made it easier and more diversified to proce or contribute content to the Internet, thus enhancing the enthusiasm of Internet users to participate in the contribution and recing the threshold of procing content. Eventually, every netizen becomes a tiny and independent information provider, making the Internet more flat and content proction more diversified.

3. One of the characteristics of media theory is the wide ambiguity of various views. On the relationship between media and society, one of the focuses of the debate is the theoretical debate between "media centric" and "social centric", First, the view of "media center" lays particular stress on the field of media activities. It holds that the mass media, influenced by the irresistible driving force of the development of communication technology, has formed an independent force beyond the law of social movement. Mass communication has its own mode of operation and logic, highlighting the autonomy and influence of the media“ The view of "social center" regards the mass media as the reflection of political and economic forces, and holds that the media, just like its original intention, is only the carrier of information transmission. Therefore, the media theory is only a special application of the larger social theory. Second, the "media center" theory holds that the mass media has the ability to "acculturate" and "cultivate" the society, And regard the mass media as the main instigator of social change“ The theory of "social center" holds that media is always under the influence of social forces. It belongs to society and bears special responsibility for society. It is not difficult to see that the differences between theories are irreconcilable e to different footholds

4. . I began to understand how large-scale tasks can be accomplished through a decentralized approach with minimal rules; I've learned that not everything has to be planned in advance. The picture of the traffic on the streets of India has always been in my mind: the bustling crowd, the standing cattle, the drilling bicycles, the slow cattle cart, the speeding motorcycles, the huge trucks, the crashing buses - the traffic mixed with sheep and cattle wriggling on the road with only two lanes, but each other is at peace. Asia has given me a new perspective.

5. Not necessarily, centralization is only for the convenience of explanation, and does not affect the regression coefficients Central treatment of regulatory effect of South Heart Network

6. Centralization means subtracting the average
