Awareness of the need has recently emerged, but still no integrated resource management system is universally accepted. A fragmented management approach has not been effective. Any successful course of action must be based on three assumptions: (1) that science can determine how ecosystems function, (2) once this is known, the social/political system will be able to protect ecosystems to the extent needed for the survival of human society, and (3) reality will take precedence over political expediency because Mother Nature cannot be fooled. This discussion focuses on the transition from awareness to taking effective action.展开更多

In the context of the enterprise, which does not have the motivation to take the initiative to improve the environment, we realize the importance of environmental consciousness. The necessity of the incentive of the environmental awareness will be elaborated by psychology aspect. In the meantime, some suggestions are advanced in knowledge and experience, government policy and financial institution fields, to really motivate the China＇s environmental consciousness, to really change environmental protection problem into the internal problems of the enterprise. Finally, it can enable the enterprises to protect environment actively, and promote the smooth implementation of environmental accounting.展开更多

By providing a conceptual framework based on the combination of environmental awareness theory and tourist perception theory, and a SEM-based methodology, an in-depth analysis of the influence mechanism was carried out in the Qinghai Lake area of Qinghai province. Results show that there exist differences in the ways environmental awareness influences perceived gains and perceived losses, and the influence coefficient of the former is higher than that of the latter. The perceived gains may promote environmentally friendly behaviors, while the perceived losses have an adverse impact on such behaviors. Moreover, the strength of the adverse impact of the latter is less than the strength of the positive impact of the former. The mediating effect of perceived quality was confirmed in the EA（environmental awareness）-EB（environmental behavior） nexus, within which the influence of tourist environmental awareness on environmentally friendly behavior could be transformed. The mediating effect of perceived quality in the perceived-gains model was more obvious than that in the perceived-losses model. This study highlights the importance of understanding the foundations of environmental behavior related to environmental awareness and tourist perceptions.展开更多

Unfortunately, these campaigns do not always lead to the upgrading of people＇s pro-environmental behaviors, because people＇s behaviors are usually based on various motivations, including economic efficiency, convenience and so on. This article mainly aimed at analyzing the implementing reasons of people＇s pro-environmental behaviors and finding out policies of promoting people＇s pro-environmental behaviors. Therefore, the author conducted the internet investigations among male and female respondents over 20 years old, and collected valid responses of more than 1,000 from 2008 till 2014 every year in Japan and also used three communication concepts, which are the direct communication, the indirect communication and the direct and indirect combined communication as a framework for discussing policies of promoting people＇s pro-environmental behaviors. As a result of the internet investigations, it was found that non-environmental factors, such as ＂saving the household＂, ＂compliance with social norms＂ and ＂health＂ were bigger than the environmental factors, such as ＂the prevention of the global warming＂ and ＂saving resources＂ with regard to the implementing reasons of the pro-environmental activities. Actually, the pro-environmental activities often have the non-environmental benefits, such as cost-saving, health and so on. And so, the author suggests that it is effective that upgrading the implementation rate of the pro-environmental activities do not only appeal to the effects of reducing the environmental loading that the activity has （the direct communication）, but also to the non-environmental benefits that the activity has, especially it is true to unconcerned people about environmental issues （the indirect communication）. In addition, the author emphases that people need to appeal to both the environmental effects and the non-environmental benefits which the activity has, respectively, especially to people with the concern about environmental issues to some extent （the direct and indirect combined communication）.展开更多

In this context,the ecological civilization has been put on the agenda. Taking Ningshan County in Shaanxi Province as an example,through questionnaire,this paper interviewed and studied environmental behavior of local urban residents. It carried out analysis on the environmental knowledge,environmental awareness,community environmental norms,environmental laws and regulations,and environmental behavior. In conclusion,with changes in environmental behavior,urban residents of Ningshan County should further strengthen their environmental awareness,and government should further improve the environmental improvement policies,make reasonable planning of communities,so as to promote improvement in the overall environmental awareness and changes in environment behavior.展开更多

文摘Brazil is the largest consumer of pesticides worldwide. Public health studies in Brazil show that inadequate use of pesticides increases the incidence of accidents and contamination of poor rural communities. This study sought to identify factors that determine the occurrence of problems with pesticides in a typical Brazilian land reform settlement. The study was carried out in Caiaponia, Goias state. In the empirical analysis, the econometric model pro bit was used. The dependent variable was the existence of health problems in the family setting that are caused by pesticides. The independent variables were the family size; the attendance to any church, whether Catholic or Protestant; if farmers received any technical assistance; the current health condition of the family, and if there are exacerbated erosion problems on the farm. Data from 28 farmers were collected through a structured questionnaire. Among the main findings, larger families have a higher probability of accidents involving pesticides. The current healthy conditions of family and the problems of soiled gradation in the farm imply are duction in the likelihood of contamination with pesticides. These two results indicate that rural households that have good health condition and have experienced environmental degradation on their farm have higher environmental awareness.

文摘In the rapid industrialization and urbanization of China,the damage of ecological environment hinders the people's pursuit of good environmental quality.As a technical means of ecological environment protection,the assessment of ecological environment damage has been attached great importance by all walks of life.However,there are still some problems in the current practice of environmental damage assessment.Therefore,based on the understanding of ecological environment damage assessment and related concepts,this study systematically studies the theory of ecological environment damage assessment.Based on the research,it can be seen that the assessment of ecological environment damage is the inevitable product of social and economic development and the promotion of environmental protection awareness,and ecological environment damage belongs to the subordinate concept of"environmental damage".The assessment of ecological environment damage includes the assessment of ecological damage and environmental damage,paying attention to the interests of human society and the unclaimed pure environment and pure ecological damage.The assessment of ecological environmental damage determines the goal and direction for the construction of environmental damage compensation system.This study enriches the theory of environmental damage assessment and provides theoretical reference and method basis for environmental damage assessment.

文摘This article puts forward four aspects for moving to-wards the city:Moving towards compositional frame—respect,ad-just,safeguard and create cities and group structures:moving to-wards the future—this requires“looking back”and“looking for-ward.”to form diversified and harmonious groups;moving to-wards the engineering svstem—becoming an organic componentpart of city road traffic,topographical readjustment,preventing andfighting natural disaster systematic projects;moving to the soft envi-ronment—satisfying the demands of urban economic and social de-velopment,history and culture,and customs and habits.
文摘One of the limitations of current content delivery networks is lack of support for environment aware content delivery. This paper first discusses the requirements of such support, and proposes a new metadata gateway based environment aware content delivery architecture. The paper discusses in some details key functions and technologies of environment aware content delivery architecture, including its APIs and control policies. Finally the paper presents an application to illustrate advantages of environment aware content delivery architecture in the context of next generation network.

文摘A systematic solution is developed to improve the autonomous capability of the quadruped robot with a manipulator,such as navigation,recognition and operation.The developed system adopts novel software,hardware system and system architecture,including a specially designed environment awareness system(EAS).Based on the camera and LiDAR on the EAS,the recognition of multiple common targets,such as the leader,door,window and bag,is achieved.In terms of navigation,a location method is built,that combines the laser odometer and global positioning system.A mapping and path planning module is designed by the Robot-centric Elevation Mapping algorithm and the rapidly exploring rand tree algorithm.For operation,a real-time target grasp detection system is proposed based on the You Only Look Once v5 algorithm to improve the success rate of tasks.The whole system is integrated based on the task relevance scheduling strategy to reduce the computational complexity.The tightly integrated system and the subsystems are evaluated by conducting simulations and physical experiments in robot recognition,navigation and operation.Extensive experiments show that the proposed framework can better achieve the autonomous navigation and operation of the quadruped robot with a manipulator.Notably,the proposed framework is still effective when facing dynamic objects.In addition,the system can be easily extended to other forms of mobile robot.

文摘Investment and technology cooperation has become prevalent among manufacturers for reducing carbon emission.However,the success and sustainability of such cooperation can be restrained by firm opportunism.This study investigates the impact of three different cooperation modes(CER investment cooperation,information sharing cooperation,and comprehensive cooperation)on manufacturers’efforts for carbon emission reduction(CER).We also analyze how opportunism in key resources input affects the CER cooperation,and explore the influence of carbon tax and consumer environmental awareness(CEA)on opportunistic motivation.Our results show that 1)Manufacturers engaged in cooperation will increase their profits,but may not necessarily lessen carbon emission,which is related to the intensity of market competition.2)The optimal mode for manufacturers is comprehensive cooperation,followed by information sharing cooperation,and then is CER investment cooperation.3)Opportunism is not necessarily detrimental to CER.4)In the comprehensive cooperation mode,the impact of opportunism to the co-operative manufacturer is hierarchical,and whether the cooperation continues depends on the intensity of market competition.5)CEA will encourage the opportunism,while the effect of carbon tax on opportunistic motivation is related to the market size.
