Social Promotion Mechanism under the Dai People’s Traditional Worship of“Dragon Forest”

“Dragon Forest”culture has a long history,and it is the oldest and most primitive traditional culture of the Dai Nationality.As the holy forest of the Dai Nationality,“Dragon Forest”is the resting place for the souls of the“Meng God(tribal ancestor)”and“Zhai God(clan ancestor)”of the Dai people.Dai people not only respect and worship“Dragon Forest”,but also set up a temple in“Dragon Forest”and hold sacrificial activities regularly,to pray for health and happiness from their ancestors.“Dragon Forest”is the combination of multiple factors,and has been continuously protected by worship and taboo for thousands of years.It combines closely the natural system,belief system and social culture system,becomes a place that supports people’s ideas,values and spirits,and solidifi es into a structural force in the social structure,which plays a certain role in promoting the social mechanism of local village community.

China’s Consultation Mechanisms during Social Transition——Speech at the Symposium on the Tenth Founding Anniversary of the Tokyo Foundation

I am happy to attend this symposium at the invitation of the Tokyo Consortium. China and Japan are close neighbors, separated only bya narrow strip of sea. Exchanges have been frequent between the Chinese and Japanese peoples since ancient times. In striving for modernization,

Understanding the mechanism of social tie in the propagation process of social network with communication channel

The propagation of information in online social networks plays a critical role in modern life,and thus has been studied broadly.Researchers have proposed a series of propagation models,generally,which use a single transition probability or consider factors such as content and time to describe the way how a user activates her/his neighbors.However,the research on the mechanism how social ties between users play roles in propagation process is still limited.Specifically,comprehensive summary of factors which affect user’s decision whether to share neighbor’s content was lacked in existing works,so that the existing models failed to clearly describe the process a user be activated by a neighbor.To this end,in this paper,we analyze the close correspondence between social tie in propagation process and communication channel,thus we propose to exploit the communication channel to describe the information propagation process between users,and design a social tie channel(STC)model.The model can naturally incorporate many factors affecting the information propagation through edges such as content topic and user preference,and thus can effectively capture the user behavior and relationship characteristics which indicate the property of a social tie.Extensive experiments conducted on two real-world datasets demonstrate the effectiveness of our model on content sharing prediction between users.

Social and cultural dimensions of rodent pest management

Rice production in Vietnam is threatened by rodent pests, with a significant increase in impact reported from 1990through to the early 21st century. Pre-harvest rice losses are typically 5–10%, with losses of >20% occurring insome years in some regions. Farmers’ rodent control practices are generally reactive and rely essentially on chemicaland physical methods. Ecologically-based rodent pest management (EBRM) was developed in the late 1990s tomanage rodents in rice-based farming systems in Vietnam and other parts of South-East Asia. EBRM combinesboth cultural and physical rodent management practices such as synchrony of cropping, short 2-week rat campaignsat key periods in key habitats, increasing general hygiene around villages, and use of a communitytrap-barrier system. Although EBRM has been reported to be economically profitable, the successful adoption ofthis set of technologies requires community participation. In this paper we address issues relating to the adoptionand sustainability of EBRM in lowland irrigated rice fields in the Mekong Delta in Vietnam. We particularly explorethe social and cultural mechanisms involved in maintaining community participation to further understandthe conditions under which EBRM works and does not work. Positive indications of sustained use of community-based EBRM include: a policy pronouncement from the prime minister directing the use of integrated rodentmanagement;the use of existing cooperatives for developing community actions;budgetary allocation fromprovincial and local governments;diffusion of EBRM to provinces in the south and north that are not involved infarmer participatory field trials;and the adoption of EBRM by a non-governmental organization, World VisionVietnam, in their area-development programs.

Privacy-Preserving Strategyproof Auction Mechanisms for Resource Allocation

In recent years, auction theory has been extensively studied and many state-of-the-art solutions have been proposed aiming at allocating scarce resources. However, most of these studies assume that the auctioneer is always trustworthy in the sealed-bid auctions, which is not always true in a more realistic scenario. Besides the privacy-preserving issue, the performance guarantee of social efficiency maximization is also crucial for auction mechanism design. In this paper, we study the auction mechanisms that consider the above two aspects. We discuss two multi-unit auction models： the identical multiple-items auction and the distinct multiple-items auction.Since the problem of determining a multi-unit auction mechanism that can maximize its social efficiency is NPhard, we design a series of nearly optimal multi-unit auction mechanisms for the proposed models. We prove that the proposed auction mechanisms are strategyproof. Moreover, we also prove that the privacy of bid value from each bidder can be preserved in the auction mechanisms. To the best of our knowledge, this is the first work on the strategyproof multi-unit auction mechanisms that simultaneously consider privacy preservation and social efficiency maximization. The extensive simulations show that the proposed mechanisms have low computation and communication overheads.

Enabling Open Innovation:Lessons from Haier

Open innovation has become a dominant innovation paradigm.However,the actual adoption of open innovation organizational designs and practices remains elusive,and ongoing examples of large companies practicing open innovation in mature industries or beyond R&D activities are rare.Despite the continuing interest in open innovation and the surging research on the topic,not much is documented about how,in particular,large companies interpret and implement open innovation or develop and sustain an innovation‐enabling culture.This paper reports on a study of Haier’s adoption of six radical innovations as it implements an open innovation organization over a period of seven years.The study is unique in that the cases reveal how open innovation is enabled by the socially enabling mechanisms developed under Chairman Ruimin Zhang’s leadership.These varied enabling mechanisms open the organization to serendipity at every level,from the bottom up to suppliers.Most importantly,the mechanisms imprint and sustain an open innovation culture recognized as important—yet often left unarticulated in terms of how it is practiced—in the prior literature.The paper contributes to and highlights the centrality of socially enabling mechanisms underlying an organization’s innovation absorptive capacity.
