The increase of land area alleviated the contradiction of supply and demand between human and land, which provided the guarantee for agricultural production and industrial development. However, marine ecological environment has been seriously damaged due to the increasing scale of tideland reclamation. This paper took the Hangzhou Bay in the Yangtze River Delta as a study area to explore the evolution law, socioeconomic effect and eco-environmental effect of reclaimed land from 1985 to 2015. The result showed that as follows:(1) The area of tideland reclamation was 460.67 km^2 with 16.57% cultivated land and 15.93% construction land, and its land use was inefficient;(2) Land use change has spatial and temporal difference, the speed of tideland reclamation had been increasing from 1985 to 2015 in time and the scale of reclaimed land in the southern(84.07%) of Hangzhou Bay was larger than the northern region(15.93%) in space;(3) The evolution law of land use was from tideland to swampland and coastal waters to agricultural facility land, to cultivated land to industrial-mining land to idle land, rural-urban construction land, and formed obviously hierarchical structure;(4) Effect analysis of land use change found that the socio-economic effect had increased but the eco-environmental effect had decreased from 1985 to 2015, it reflected socio-economic effect was acquired through sacrificing eco-environmental effect;(5) It pointed out the existing problems on land extensive inefficient, environmental degradation and economy excessive growth without scientific planning, and offered some suggestions in land comprehensive improvement project, industrial transformation and upgrading and scientific planning and legal safeguardto promote sustainable development in the Hangzhou Bay in the new period.展开更多

Although there have been numerous efforts to eliminate cracks, some cracks are very harmful and should be repaired as soon as possible. On the other hand, some cracks are almost harmless. So, a good guideline regarding how to deal with cracks in concrete structures is needed. In this guideline, the practical investigation, repair and strengthening method of cracked concrete structures is discussed. And the detecting subjects are cracks generated immediately after casting and during the service time. This guideline targets on the owners (including managers) of concrete structure and the engineers working for the maintenance of concrete structure. JCI (Japan Concrete Institute) published first version of "Practical Guideline for Investigation and Repair of Cracked Concrete Structures" in 1980, and then the fourth version titled "Practical Guideline for Investigation, Repair and Strengthening of Cracked Concrete Structures--2009" was published. This guideline is very practical when cracks are observed in existing concrete structures, in any other countries as well as in Japan. These three authors led the establishment of this guideline.展开更多

The purpose of the study is to quantify social-economic well-being development with special emphasis on poverty. The maximum entropy bootstrap was presented that did not require the property of stationarity. Moreover, the methodology was stratified both the ergodic theorem and the central limit theorem. Thailand's GINI index and Thailand-Japan's volume of trade data cover the 14-year period from 1998 to 2011. There is a statistically significant negative non-linear relationship between endogenous Thailand's GINI index and exogenous Thailand-Japan's volume of trade. The results confirmed that every lagged one percent increase in Thailand-Japan's volume of trade influenced by a decrease of Thailand's GINI index coefficient 0.039 percent with the asymmetric around 0-almost closed to range condition -0.034824348 at 2.5%.展开更多

Increasingly, social risk is being recognized as a key factor determining the success of a mineral investment. Groups opposed to a mine for social or political reasons otten use environmental impacts, real or perceived, to prevent mine development. These risk factors depend largely on cultural perceptions of mining activities and must be understood as such in order to be appropriately managed. A first step to addressing social issues is inclusive, transparent and meaningful engagement of stakeholders. This process allows stakeholders to understand what the other parties value in order to collectively establish a common currency for development and the creation of mutual value. Expanding the scope of benefits and values a mine can bring is of increasing importance to mining companies who typically consult outside specialists remote from the mine site and late in the development timeline for this purpose. Training technical staff, engineers and geologists, who make initial and ongoing contact with local interests, in a holistic approach to mine development is crucial to successful and economic mineral development projects. Further extending this conversation to the genera/ public, media governments and non-govemmental organizations is a necessary step in developing a meaningful discourse on the benefit of mining activities.展开更多

Therefore it is of great practical importance to probe the rules of the effect from coal resource exploration on arable land. Suitable and effective measures to compensate for damaged to and loss of arable land resources should be taken on the basis of carrying out green mining and reducing damage to limited arable land resources. We have used GIS in simulating the effect of coal resource exploration on arable land. In light of our simulation of the space-time spectrum, the effect is analyzed. Given the socio-economic development conditions of a mining area, specified rational amounts and opportunities for compensation to arable land in mining areas are explored. Finally, from a policy perspective, relevant proposals for rational arable land resource compensation are proposed to facilitate the coordinated development between coal resource exploitation and socio-economy development in mining areas.展开更多

With the further improvement of the socialist market economy, the existing sports administrative functions are incompatible with the economic and social side of the market gradually. The current sports administrative functions can no longer adapt to the development and deeper reforms of sports system are imminent. Only by speeding up the reform of sports administration, can eliminate obstacles and promote rapid and healthy development of China's sports industry. In this paper, the object is the administrative functions of the sport in the social transformation period, through expert interviews, literature, and logical analysis, comparative study to discuss the problems of the administrative functions of sport in the social transformation period and propose appropriate countermeasures. Studies suggest that: sports administration departments should focus to implementing national policies, the development of the sports industry policy research and development planning, management and delivery of services. In accordance with the uniform principles of responsibility, rights and interests, to further clarify the responsibilities of all levels of sports administration, handling good working relationship between them. By Complete separation between rowing and steering, governance and administration, government and industry, to achieve "four transformations", and to break plan "all-round" type of government in the economic system, and establish "limited" government, effectively carry out the functions of guidance, policy regulation, market supervision, social management and public services.展开更多

Africa has as well received year-on-year increases in foreign aid from China as compared to Latin America and Asia. This paper seeks an analysis of the increasing economic and social ties between China and Africa. Employing the political economy framework, this paper uses secondary sources of data to rake out the benefits and the threats as well as the political dynamics associated with the ties between the two regions. The paper reveals that China's deep-rooted relationship with Africa is translated in benefits including foreign aid, Foreign Direct Investment (FDI), construction of physical amenities and human resource development for Africa. However, enormous threats including loss of employment, deprivation of human rights and collapse of industries, which are being entrenched by various degrees of leadership deficiencies, are apparent. The paper concludes that the ties, in terms of nature and effects, do not essentially represent change from the already existing ties between Africa and the West but only represent continuity in the dependency syndrome with a new "benefactor-exploiter". The solution for Africa, as the paper suggests, does not lie in closure of ties with China but in a knowledgeable, willing and action-oriented leadership which can consolidate the benefits and reverse the threats emerging from the ties.展开更多

The multiple dimensions and scales of socioeconomic dynamics pose numerous challenges for the application and evaluation of public policies in the comparative context. At the same time, social scientists have been slow to adopt and implement new spatiotemporally explicit methods of data analysis due to the lack of extensible software packages, which becomes a major impediment to the promotion of spatiotemporal thinking. The proposed framework will address this need by developing a set of research questions based on space-time-distributional features of socioeconomic datasets. The authors aim to develop, evaluate, and implement this framework in an open source toolkit to comprehensively quantify the changes and level of hidden variation of space-time datasets across scales and dimensions. Free access to the source code allows a broader community to incorporate additional advances in perspectives and methods, thus facilitating interdisciplinary collaboration.

It analyzes the social practice of everyday life in one of the oldest Cairene hawari, Haret al Darb al Asfar. The focus is on architectural and spatial organization of outdoor and indoor spaces that coordinate the spatial practices of local community. A daily monitoring of people's activities and interviews was conducted in an investigation of how local people perceive their built environment between the house's interior and the outdoor shared space. It emerges that people construct their own field of private spheres according to complex patterns of daily activities that are not in line with the classical segregation between private and public in Islamic cities. This paper reports that the harah is basically a construct of social spheres that are organized spatially by the flexible development of individual buildings over time and in response to changes in individuals' needs and capabilities. In order to achieve sustainability in old urban quarters, the paper concludes, the focus should be directed towards the local organization of activities and a comprehensive upgrading of deteriorating buildings to match the changing needs of current population.展开更多

Efficient investments often do more with less. Manufacturing enterprises should pay more attention to the issue of investment efficiency, seize investment opportunities and achieve efficient investment. Due to the continuous increase of borrowing costs in the financial markets, enterprises are getting more and more difficult to raise funds from the outside, so more and more enterprises are turning their attention to the financially redundant resources within the enterprises. Making good use of financially redundant resources will help enterprises solve the financing difficulties and enable them to have sufficient funds for investment activities and lay the foundation for sustainable development.展开更多

And in the world community, now prevalent idea of democracy with equal rights and freedoms for all citizens of a democratic state is a risk and a challenge to the integrity of a community. Against this background, it becomes important not only process control, but also a system of communication between society and the state. For effective interaction between society and the state, the government needs a new, streamlined platform for the provision of public services. This site was e-government. Currently, the concept of "open government" is implemented in the administration of the state in all developed countries. This paper deals with modern communication mechanism of the state and society in Russia, for example, "e-government", and the effectiveness of this mechanism in the process of changing demands of society.展开更多

People's understanding of the relationship between economy,society, and environment has been continuously deepened over the years. When it came to the end of 2015, it is necessary to examine the results of the United Nations Millennium Development Goals on sustainable development, and at the same time, the post-2015 framework and guidance on sustainable development at the global level were to be made, including the ideas, action plans, key areas that would guide the global sustainable development. The 2030 Agenda for Sustainable Development has developed a 5P theoretical framework of being peoplecentered, global environmental security, sustained economic prosperity, social justice and harmony and partnership promotion, including a political declaration, 17 overarching goals and 169 specific targets, specific ways of implementation, as well as the follow-up. It is the road map to achieve global sustainable development and meet the requirements of the millennium development goals. This paper summarizes the understanding of the concept of sustainable development from its origin, its significant development, to the proposition and development of the 2030 Agenda for Sustainable Development, and its strategic impact on China.展开更多

文摘Tidal currents are a resource of great potentiality and not yet fully explored. Several efforts have been made to exploit these resources, but the costs associated to the deployment of tidal plants in marine environments are usually too high. The aim of this work is to present a system able to handle with the above mentioned problems, through the development of a particular hydrokinetic turbine design. In previous works, the authors described a basic turbine configuration achieving interesting performances, although some operational inconveniences were detected. Those problems have been existing so the solution should be optimized and redesigned. As a result, a new design of the turbine is proposed, consisting of a double rotor spinning in opposite directions in order to balance the induced mechanical torque.
