Main Factors on Energy Efficiency in East China during 1995-2010： An Analysis Based on the SBM-Tobit Model

Applying the slacks-based measure （SBM）-Tobit two-stage model, this paper analyzes energy efficiency in eastern China. First, the SBM model featured in taking non- desired output in calculation was employed to evaluate the energy efficiency in eastern China from 1995 to 2010. The results show that Tianjin, Shanghai and Guangdong have the highest energy efficiency while Hebei has the lowest. Next, we used the panel Tobit model to perform a regression on factors affecting energy efficiency. Our results show that optimizing industrial structure, improving energy structure and enhancing the level of economic reform can contribute to improving energy efficiency. Government influence and technological progress, on the other hand, affect energy efficiency insignificantly. The influence of socio-economic development on the energy efficiency goes from negative to positive, which adheres to the Kuznets curve hypothesis. Our findings are that the socio-economic development in eastern China has not yet passed the ＂turning point of the Kuznets curve ＂.

＂Beyond the Dreams of Loveliness＂ --Film, Unionism, and Working Class Community Formation in Detroit, 1933-1939

Ever since Lawrence Goodwyn published The Populist Moment, social historians have been keenly aware of the power culture represents when it comes to resistance. Historically, ＂movement culture＂ has been used to create a collective climate and offered political activists a springboard to discuss with the masses the benefits of joining a social movement. ＂Beyond the Dreams of Loveliness＂ uses the cultural outlet of film and the labor movement in the city of Detroit as analytical tools to examine working class community resistance throughout the 1930s. In the midst of the ＂golden age of film＂ community activists and union organizers--some of whom were well-known radicals and some of whom were mainstream unionists--used the institution of cinema to instill a level of class consciousness in the masses and mobilize the working class community against exploitation of employers, reactionary politicians, and white supremacist organizations. Movie-going had been a very popular form of recreation in Detroit since the 1920s and downtown theatres increasingly became the destination of an eclectic array of workers. Movie theaters themselves were bastions of community activity around the thirties and many were located in the heart of the city＇s working class district. Yet it was the films themselves that offered community activists and unionists a chance to converse with workers regarding the socio-economic matters of the day. Hollywood released a good number of films that dealt with working class issues and provided activists with ample opportunities to ＂instruct＂ the audience and carry on the discussion into the factory or union halls. ＂Beyond the Dreams of Loveliness＂ relies on a combination of oral histories, movie reviews, film clips, and union and/or working class organizational records to illuminate how activists in Detroit＇s working class community used film as an outlet to inspire working class resistance. In sum, film provided an accessible form of entertainment that proved to be effective on two fronts： It promoted increased group cooperation, friendship, and alliances while it also fostered a shared culture, making it easier for activists to organize workers in the coming struggles for unionism.

Economic Characteristic of Coastal Community at Mining Region, Kotabaru Regency, Indonesia

Economic development of coastal community in Kotabaru Regency has become strategic in the future. Kotabaru Regency is the geo-economic strategic position due to the position of Kotabaru region boundaries between Kalimantan Island and Sulawesi Island. Geo-economic strategic of Kotabaru should increase the coastal community welfare in Kotabaru Regency. The objective of the research is to evaluate economic characteristic of coastal community at mining area in Kotabaru Regency. The number of samples in this study is 50 respondents in each village who are in the mining area. The number of companies in the mining area is 17 companies. Data were collected by using questionnaires. The results show that economic characteristics have low category. Mining and plantation companies do not increase the economic conditions of the community. Research suggestions are： （1） to examine the potential and importance of economic empowerment model of coastal communities in the region both mining companies and plantations; （2） the important role of companies and local governments to work together in formulating a strategy for management of CSR （corporate social responsibility）, and social mapping to be done by the company in the preparation of the CSR program.

Evolution and Effects of the Social-ecological System in Karst Mountainous Regions:A Case Study of Guangxi,China

Karst regions are the typical areas of interaction between human society and natural ecosystems.Understanding the historical mechanisms of the evolution of social-ecological systems(SES)is crucial for the future sustainable management of karst regions.This study selected Guangxi,a typical karst mountainous region in Southwest China,as the study area,and used population,cropland area,and forest coverage as the SES elements.Based on the framework of SES research in the karst region,it adopted segmented linear regression to identify the stages of the interactions among these elements,to reveal the evolutionary stages of social development from the long-term perspective.In addition,the driving factor indicators were constructed from the aspects of natural environment,social development,government policy,and climate change,and then the feedback changes brought about by the evolution were investigated.The results show that the evolution of SES in Guangxi from 1363-2020 can be divided into seven stages.In the first,second,and early period of the third stages,the government of Guangxi mainly focused on agricultural activities,although the only way to meet the growing demand for food was by expanding the area of cropland,and the timber trade’s pursuit of economic development,resulting in an increase in rocky desertification.In the fourth stage,the ecological environment improved under the implementation of measures such as the control of rocky desertification and the compensation of forest ecological benefits.After the fifth stage,the effect of rocky desertification control has been remarkable.Although the implementation of relevant policies has alleviated the environmental problems to some extent,the continual changes in the structure and function of SES can challenge further progress towards sustainability in karst regions.This study aims to provide a reference for the long-term national spatial planning and the development of environmental policies in karst regions.

Feature Analysis and Modeling of the Network Community Structure

Community structure has an important influence on the structural and dynamic characteristics of the complex systems.So it has attracted a large number of researchers.However,due to its complexity,the mechanism of action of the community structure is still not clear to this day.In this paper,some features of the community structure have been discussed.And a constraint model of the community has been deduced.This model is effective to identify the communities.And especially,it is effective to identify the overlapping nodes between the communities.Then a community detection algorithm,which has linear time complexity,is proposed based on this constraint model,a proposed node similarity model and the Modularity Q.Through some experiments on a series of real-world and synthetic networks,the high performances of the algorithm and the constraint model have been illustrated.
