A Brief Reading of American Urban Culture in Post-Industrialization Era

In the wake of great expansion of cities as centers of production,the post-industrialization era saw American urban tran-sitions and transformations with cultural diversification highlighting consumption,service,marketing and cultural integration.Cul-tural variations in cities,under the influence of non-material production,constantly worked for urban re-invention and urban re-newal,facilitating and expediting a high-level urban development.

Post-industrial Economic Restructuring and Wage Inequality in Urban China, 2003-2015: A Sectoral Perspective

Income inequality in urban China has attracted growing attention from China’s urban researchers and policy makers. Whereas many studies have interrogated the pattern and process of the income gap in Chinese cities undergoing the institutional transformation from plan to market, relatively little is known about how such unequal distribution of income is related to China’s ongoing structural transformation toward a post-industrial economy. Drawing on a decomposition methodology based on the Theil index, this study aimed to address this lacuna through an empirical investigation of China’s urban wage inequality from a sectoral perspective. Our empirical study identified the low-wage manufacturing sector and the high-wage producer services sector as the two biggest contributors to urban wage inequality in China. Urban wage inequality within the producer services was found to be caused by the spatial concentration of a disproportionate number of high-paying jobs in a few developed, high-tier city-regions on the eastern coast. Our empirical findings have important implications for the formulation of policies to address the income inequality that plagues China’s continuing urbanization.

Investigation of soil and groundwater environment in urban area during post-industrial era: A case study of brownfield in Zhenjiang, Jiangsu Province, China

With the adjustment of industrial structure,many high pollution enterprises will gradually shut down.This process will produce a large number of high-risk pollution plots and cause a series of environmental problems.In this study,geophysical detection and direct push technology were applied to investigate soil and groundwater pollution in a typical brownfield in Zhenjiang,Jiangsu province,China.The results showed that Chlorotoluene and its ramification were the main pollutants for the brownfield.Pollution decreased with depth and was quite uneven in the brownfield.Production and wastewater treatment areas were heavily polluted,where volatile organic compounds contaminated and semi-volatile organic compounds were found 12 m and 15 m below the land surface,respectively.About 18880 m3 groundwater was contaminated.This study is significant to develop a geological survey work mode for the postindustrial era.

The Inner Link Between Economic Globalization and the Formation of American Post-industrial Economy

Economic globalization has a very important impact on the world economic development.The economic globalization,especially after the 1970s,not only promoted the global industry division of labor,but also changed the economic structure of the world.From the perspective of global industrial division,many counties have entered post-industrial process,the United States is a case in point.However,economic globalization is an abstract conception,which it consists of trade liberalization,capital globalization,and production decentralization.Therefore,trade liberalization,capital globalization,and production decentralization are important factors for the formation of the post-industrial economy in the United States.

Development and actualization of brownfields database with the use of unmanned aerial vehicles-the case of Upper Silesia,Poland

This paper presents the assumptions and the preliminary results of the project entitled"Extension of the system for man-agement of post-mining areas in the Silesian province-OPI TPP 2.0".The overall objective of the project is to develop and implement a new e-service in the form of an open-access information system on post-mining areas in the Silesia Voivodeship.The range of information and tools planned to be made available is dedicated to assessing the possibilities and potential for economic and social reuse of these areas.The basic and extremely important stage of the project was to identify and collect data on post-industrial sites located in the Silesia Province.The information contained in this article illustrates the activities that were carried out in the initial phase of the project in which unmanned aerial vehicles(UAV)were used to identify and acquire information on brownfields(including post-mining sites)entered into the developed common database.The article assesses the possibility of using drones in an enterprise of such a large scale and also points out the advantages of using this method.The article describes the methodology and scope of work related to the acquisition of data that can be collected using unmanned aerial vehicle(UAV)covering surface infrastructure and land use of brownfields,allowing for the identification of negative phenomena on their site as well as monitoring of naturally occurring processes.Based on fieldworks experience and the results of numerous analyses carried out for different types of brownfields(e.g.post-mining areas,former transport bases,settling ponds,etc.),paper presents the advantages and benefits of drones(UAN)over other data sources used to monitor changes in an area.The article is based on the results of an inventory of over 600 brownfields located in Upper Silesia region(Silesia Voivodeship,Poland).
