Of particular concern here are chemicals that can disturb an organism＇s endocrine system. Referring to the precautionary principle, the objective of the research project start2 is to develop management strategies that help reduce possible risks for httmans and the environment of endocrine active agrochemicals. As an empirical basis we combined qualitative and quantitative methods and initiated two expert dialogues. Our findings underpin the well known fact that the use of agrochemicals is complex and dependent on more than the individual attitudes of farmers. Agricultural plant protection management is the collective product of a complex agricultural system, which encompasses treatment, marketing, industry and agricultural consultation as well as agricultural teaching institutions and relevant scientific disciplines. Successful management strategies for risk reduction in the context of hormonally active agrochemicals thus need to involve all actors within this system. The paper proposes a strategy that promotes participation by enabling learning processes among these actors.展开更多

The concept...Countries in the world lack the ability to maintain internal independence and to cope with new external risks, sov ereign state relations based on respect for diversity are giving way to global solidarity. The concept of a community with a shared future for all mankind emphasizes relative independence along with the integration of human society and the joint liability of states. The basic principle is to recognize and respect diversity so as to maintain and enhance integration. In the discourse of a community with a shared future, we must look at human rights and the promotion and protection of human rights from a relational and symbiotic perspective. The concept of human rights is comprehensive, the universality of human rights does not mean the universality of human rights standards, and the global governance of human rights needs to strengthen both the internal c and external capacities and conditions of countries. In this regard, China’s experience is to form a task-oriented target governance model, enhance the enforceability and evaluability of the legal protection of human rights, substantiate and operationalize human rights principles and proposals at all levels through efforts such as establishing mechanisms and initiating forums, and continue to implement and enhance the external cooperation mechanism. The vulnerability, diversity, and scarcity of individuals and human societies are the roots of the problems of global peace and security, and a community with a shared future is also a community of rights, obligations and responsibilities. Therefore, the promotion and protection of human rights is not a burden to be distributed, but a responsibility to be shared, a collective responsibility based on shared values.展开更多

The Universal Declaration of Human Rights is an important document in the development of the international human rights cause. It established a set of international standards for basic human rights, represents the world’s most important consensus on human rights, and contributes greatly to the creation of an international human rights legal system. The important theory put forward by President Xi Jinping to build a Community with a Shared Future for Human Beings, as a Chinese program for today s global major issues, also outlines a new blueprint for national human rights protection and will play a major role in promoting the development of China’s human rights and international human rights protection.展开更多

They not only provide users with convenience, but also bring many security issues, such as data sharing and privacy issue. In this paper, we present an access control system with privilege separation based on privacy protection(PS-ACS). In the PS-ACS scheme, we divide users into private domain(PRD) and public domain(PUD) logically. In PRD, to achieve read access permission and write access permission, we adopt the Key-Aggregate Encryption(KAE) and the Improved Attribute-based Signature(IABS) respectively. In PUD, we construct a new multi-authority ciphertext policy attribute-based encryption(CP-ABE) scheme with efficient decryption to avoid the issues of single point of failure and complicated key distribution, and design an efficient attribute revocation method for it. The analysis and simulation result show that our scheme is feasible and superior to protect users' privacy in cloud-based services.展开更多

The algorithm uses the minimum cost spanning tree strategy and fuzzy game theory. First, it virtualizes two planes to calculate the multicast tree and the multicast protection tree respectively. Then, it performs a fuzzy game to form a cooperative alliance to optimize the path composition of each multicast tree. Finally, it generates a pair of optimal multicast work tree and multicast protection tree for dynamic multicast services. The time complexity of the algorithm is O(k3 m2 n), where n represents the number of nodes in the networks, k represents the number of dynamic multicast requests, and m represents the number of destination nodes for each multicast request. The experimental results show that the proposed algorithm reduces significantly the blocking rate of dynamic multicast services, and improves the utilization of optical network resources within a certain number of dynamic multicast request ranges.展开更多

The results indicated that water temperature and pH of aquaculture ponds cound meet the requirements of fish normal growth,and dissolved oxygen was rich, but the water quality was over fertilized generally. In 20 investigation spots of the five districts, the content of CODCr, NH4^＋-N and TP exceeded 90%, 30% and 85% respectively. The pollution degrees of the water quality from high to low in aquaculture ponds were Chancheng district,Nanhai district, Sanshui district, Shunde district, Gaoming district. The comprehensive quality index of aquaculture ponds was 1.44 in Foshan city, the water quality was polluted severly as a whole. The share rate of pollution load of TP was the highest, the second were CODCr and NH4^＋-N. On the whole, the pollution of organic matter was very prominent in the water quality of aquaculture ponds around the basic farmland protection areas in Foshan city that had been eutrophicated.展开更多
