The foundation of the People’s Republic of China in1949 marked the realization of a dream strived for by millions of Chinese people over the preceding hundred years,i.e.,the dream of liberation.Since 1949,China has gone through two stages of historical development,in which it realized the dream of self-reliance and the dream of freedom from poverty,respectively.Having entered the third stage of its contemporary history,China is now striving to achieve a new dream of shared prosperity for all.Supported by statistical data,this paper argues that China has made a great leap forward in the field of social protection over the past 10-plus years.This new leap forward has quietly brought about enormous changes to the Chinese society.On one hand,it has stopped inequality from further deteriorating;on the other hand,it has created a benign environment for lessening human insecurity.  相似文献

This study examines the urban population of tourism practitioners perceptions of economic, environmental, and social impacts on cultural, convention, and sport tourism may have in Haikou and Sanya. Hainan, China. The study uses a modified Urban Tourism Impact (UTI) to examine economic, environmental, and social perceived impacts. Analysis of the data includes testing three models of structural relationships between tourism impacts and support for development in each of the tourism market sub-divisions through a confirmatory factor analysis. The results of this study show that the positive economic impacts consistently exert influence on predicting support for tourism development in all three models. However; the social impacts play a greater explanatory role with all three market segment, the negative environmental impacts play a role in determining support for sport tourism only. Differences have been found with those with a higher education level in predicting support for cultural tourism, but not convention or sport tourism.  相似文献

Urban spatial growth has become a hot topic of geographic science and urban research. Exploring the patterns and mechanisms of urban growth is the prerequisite to understand the urbanization process of China. The paper provides a spatial analysis method of using Remote Sensing (RS) and Geographic Information System (GIS). and presents major patterns and mechanisms of urban spatial growth during the period from 1979 to 2007 in Nanjing City. Firstly, the paper introohwes the data, study area and methodology of the research. Then. the patterns of urban spatial growth are identified Subsequently, the main mechanisms of urban spatial growth are analyzed Finally some conclusions are drawn definitely. The features of urban spatial growth in Nanjing are as follows: during 1979-1988, urban spatial growth of each district was stow. and the inner growth was in excess of suburban growth; during the period of 1988-2000. urban growth of suburban was in excess of inner city. the most insensitive growth appeared in the southeast, and the growth of each aspect was relatively insensitive expect ecst and west; during the period of 2000-2007, urban growth of suburban was violent, the most insensitive growth appeared in the southeast. and the urban growth of each direction was insensitive except the west. The mechanisms of urban spatial growth are complex, the main ones of which are social and economic development. Besides. the guiding of urban planning and influence of urban spatial structure are quite obvious.  相似文献

Talcott Parsons was a great well-known sociologist whose approach was based on system theory. He identified social system into subsystems which were A (Adaptation functions), G (Goal gratification functions), I (Integration functions), and L (Latent pattern maintenance functions). His approach was based on the concern for the stability or maintenance of social system. The aim of this research is experimentally to identify the social system of north-east vocational education's macro administrative problems in Thailand by utilizing AGIL schema. The writer has adopted the symbiosis or maintenance of socials system stance by utilizing this approach. The results of the research were, firstly, the major macro vocational education eight problems (sentences) and 27 sub-problems (sentences) and secondly, the 15 diagrams of above-mentioned problems and sub-problems after utilizing AGIL concepts (In this paper, the writer illustrated seven of them). The study had been done using both secondary and primary data. The secondary data were collected from the written documents and from the internet concerning the vocational schools. In depth interview data were collected. Some respondents have been interviewed more than once. The total of 69 times in depth interview were collected. The researcher had utilized Japanese Kawakita Jiro Method of processing scattering paper clips from these primary and secondary data. In conclusion, the detail of main findings, system of sentences of the macro problems, some derived diagrams examples (After AGIL schema applying) and also implication from the main findings have been illustrated.  相似文献

The knowledge of a product's life cycle is the first step on the search of sustainable development. The life cycle assessment (LCA) is an important method because it allows an environment accounting, where the extraction of natural resources and energy of the nature are considered and the "returns" to the same one and allows in evaluating relative potential the environment impacts generated. The present work had as objective to make an analysis of material and energy flows of the life cycle of three types of packaging for soft drinks: glass bottles of 390 mL, aluminum cans of 350 mL, and bottles of PET of 2,000 mL. The study considered processes since the extraction of raw materials for production of the packaging until the stages of recycling, after the consumption of the soft drink. For the research, an inventory analysis followed the LCA methodology. The main critical points of generation of negative environmental impact during the life cycle of each packaging had been the identified and quantified data in this study. The consumption of natural resources like water and other raw materials and energy, the generation of atmospheric emissions, solid wastes and wastewaters had been the analyzed categories. The results showed that, in accordance with the scenes and defined variables, the most important conclusion was that the bottle of glass presented a less favorable scene to the environment in comparison with other packaging.  相似文献

The manufacturing industry today due to worldwide competition is focused on shorter development cycle. In this situation, computer aided education (CAE) technology as a tool for simultaneous achievement of quality, cost and delivery (QCD) plays an important role. The hardware-software environment surrounding CAE has evolved. Though technological problems have been understood and general solutions have been derived and reflected in the CAE analysis software, research findings that boost the credibility of CAE have still not been incorporated fully enough into the development of design process. The real technical mechanism issue is not precisely capture. Therefore, it is important to clarify the real cause in CAE results through CAE simulation in order to assure product reliability and assurance. It is the aim of this study to realize the prediction of design analysis process through understanding of unclear technical mechanism in abnormal occurrences with the utilization of CAE simulation. In other words, it is the aim of this study to focus on issue in automotive transaxle oil seal leakage to understand, grasp, and visualize the main cause through usage of CAE analysis process. It is understood that the point of contact and pump volume was related and this could contribute towards seals quality design. Plus, the utilization of CAE analysis in prediction phase to realized design development is also possible  相似文献

Based on the analysis on the status quo of natural resources input in Brain production and on the policy of Brain subsidies, this paper puts forward a new idea - establishing grain subsidies through assessing the value of the natural resources in Brain production. The assessment of the natural resources in Brain production provides rationale and reference standard for the policy of Brain subsidies, which will promote the sustainable use of natural resources accordingly. This paper concludes: (1) it is necessary for the grain subsidies to assess the full value of natural resources, including economic value, ecological value and social value: (2) the government should give farmers direct subsidies or environment subsidies according to the economic and ecological value of natural resources in grain production, (3) the social value of natural resources can be realized by establishing the country social security system, taking the social value as the criterion for the payment for part of farmers' insurance.  相似文献

A new multi-logistic methodology to analyze long range time series of evolutionary S-shaped processes is presented. It conceptually innovates over the traditional logistic approach. The ansatz includes computing the residuals to an optimized multi-logistic trend curve least squares fitted to the time-series data. The elements of the residuals series are checked for autocorrelations and once detected the residuals series is further analyzed to search for eventual presence of underlying periodic structures using a truncated Fourier sine series. The method foundations ensures both a universal applicability and a capacity to disclose the existence of active clocks that can be possibly traced to the driving motors of the evolutionary character of the time series, due to the responsiveness of corresponding process to the development of economic cycles. On associating these two views, it is found that the methodology has a strong potential to improve the quality of short-term forecasts. These findings have been put to test through applications of the methodology to studying the time evolution of two commodities of strong economic and social importance (corn and steel) and good results were consistently obtained for both the analytical and forecasting aspects.  相似文献
