Indeed, it is apparent that discourse coalitions exist both within the wind sector and the riparian corridors management. In the present study, a theoretical framework for policy power analysis is presented, while a balanced European and national energy policies representation reveals the positive and negative impacts, towards which both the above two power sources may be attributed. The “power” holistic approach is mainly determined in a wider social-economic, political, and environmental framework. This multidimensional and holistic approach is considered invaluable for humans/consumers, in order them to determine their capacities, priorities and perspectives for viable use of power within the above complex-structured framework. Finally, the study adopts a balanced reassessment of the existing policies, offering tentative proposals for reducing conflicts.展开更多

The forum has become a high-level academic platform for human rights exchanges and cooperation on the basis of equality,harmony, tolerance, openness and mutual respect, and has played an important role in promoting the healthy development of the international human rights cause? With the socialism with chinese characteristics entering a new era, the beijing forum on Human Rights needs to position new roles in the new era, seek more clear development momentum and direction, and promote the vitality, cohesiveness and international influence of the forum in a deep and all-round way and contribute to the development of world human rights cause and global human rights governance?展开更多

The core of human rights lies in the life and dignity of human beings. On the one hand, criminal procedure law is related to life and freedom, which is the concern of everybody.

To make a better China story about human rights and enhance China’s international discourse power in the field of human rights, we propose the text construction, translation and communication path of the construction of the human rights discourse system with Chinese characteristics from the cross-disciplinary perspective. Based on the examples of prevention and control of the CoVID-19 pandemic under the concept of putting people first, mainstream diplomatic linguistic data relevant to the fight against the novel coronavirus was collected through the internet. The human rights discourse with Chinese characteristics is constructed through a variety of texts focusing on putting the people first, the right to life, the right to health, the right to information, the right to privacy, the right to work and a sense of a community with a shared future for human beings. The core concepts of human rights have experienced the deepening process of decontextualization, abstraction and theorization to gradually conform to the expression habits of international audiences. The international communication effect is mainly positive in civil society. It shows that the construction of China’s human rights discourse system and the governance of international human rights discourse have achieved preliminary results. To enhance China’s discourse power on human rights, we need to add an interdisciplinary approach.展开更多

Nowadays power electronics research has added the importance of power quality studies, for concrete illustration, Custom Power Devices (CPD) and Flexible AC Transmission position (FACTS) devices. The approach offered in this paper utilizes the series and shunt compensator of Unified Power Quality Conditioner (UPQC) to inject a compensation voltage in-phase with the source current over voltage fluctuations. The execution of two structures of UPQC, left-shunt (L-UPQC) and right-shunt (R-UPQC) are investigated under diverse operating conditions based on the fuzzy logic controller to raise the value of power quality of a single feeder distribution system by MATLAB/Simulink programming. Various power quality issues have been analyzed in this study. Finally, the right shunt UPQC is outperformed in this proposed power system.展开更多
