The Impact

The damage caused by pollution is not equal across individuals within a given population, due to the differences in pollution level and coping ability. Identifying the different impacts of environmental pollution on agricultural economic growth and the source of the pollution is of great reference significance for realizing the organic integration of ecological protection and relative poverty alleviation. This study takes marine fishery culture as an example, with the cultured products data of 53 coastal cities in China from 1994 to 2018 and empirically captures the heterogeneous effects of environmental pollution on mariculture growth by constructing a theoretical analysis framework of heterogeneity in pollution damage. Results show that the deepening of marine environmental pollution will reduce the growth rate of marine cultured output, emerging significant regional differences. Nevertheless, under the background of the complex environmental situation currently, further damages mainly derive from the difference in the ability to deal with environmental pollution rather than the difference in pollution degree. In terms of different wastewater sources, the impact of industrial wastewater discharge on marine aquaculture production is not very significant. In contrast, the adverse shocks of urban domestic sewage are more prominent. Notably, the environmental pollution has a significant cumulative effect, which is not reversed. Therefore, a pollution shock in one period may leave the region permanently further behind. Based on this, in the follow-up process of pollution control, we should fully consider the heterogeneity in coping ability of individuals. While promoting industrial wastewater emission reduction, we should emphasize strengthening of the urban domestic sewage treatment strategies and give overall consideration to the ecological environment treatment and regional coordinated development.

Abstract The political incentives of local officials affect their preferences for policy options. This study examines the impact of the convening cycle of Provincial Communist Party Congresses (PCPCs) in China on pollution emission intensity. Based on the data of 281 cities and city officials from 2003 to 2014, the present study finds strong evidence of a political pollution cycle manifesting as significant increases in pollution emission intensity before PCPCs followed by visible decreases after PCPCs. PCPCs provide city officials with strong political incentives to pursue short-term economic performance before congresses, which leads to a surge in pollution emission intensity. The difference in pollution emission intensity before and after the PCPCs reveals the existence of such political incentives. The findings suggest that a significant relationship exists between the political incentives of city officials and environmental pollution. Therefore, the effective governance of environmental pollution must involve changing the incentive structure of city officials.

Abstract As one of the developing countries, China's export trade mode (ETM) has gradually shifted from processing trade to general trade. Is the deterioration of China's environmental pollution caused by the transformation of ETM? Based on the panel data from 194 cities in China from 2000 to 2016, this paper investigates the impact of ETM transformation on the environmental pollution and its internal mechanism. The results show that: the ETM is gradually shifting from processing trade to general trade, environmental pollution will deteriorate first and then improve, that is, showing a significant “inverted U-shaped” relationship between the transformation of ETM and environmental pollution. Through the robustness test of the threshold, and SYS-GMM model, the results are still valid. The mechanism research shows that the upgrading of industrial structure, energy structure, industrial agglomeration, environmental protection investment and resource allocation are the main mechanism that the transformation of ETM affect environmental pollution. The conclusions of this study can provide empirical evidence for the process that the environmental pollution level of developing countries deteriorated and then improved during the process of transforming from processing export trade to general export trade.

Purpose The purpose of this paper to investigate whether trade liberalization and the financial crisis have contributed to altering the pollution level in selected open economies of South Asia in the long run. Design/methodology/approach The study has adopted the panel data framework where results are tested using the generalized method of moments (GMM). The data of five South Asian countries from 1980–2015 have been used for computing results. Findings Owing to the globalization endeavors, the scope of energy consumption and foreign direct investment (FDI) inflows has increased significantly. The outcomes of the study reveal that globalization has significantly intensified the level of carbon emissions in the selected countries. However, the impact of financial crisis on carbon emission is found insignificant in the long run. Therefore, the study reveals that the level of environmental pollution in South Asia economies is more sensitive to positive economic variations than negative. Originality/value Earlier studies have ignored the parallel effect of globalization and financial meltdown on carbon emissions in a country or region. Stating differently, the present study intends to capture the impact of positive (globalization) and negative (financial crisis) global economic movements on carbon emissions in the five open economies. The majority of studies in the past have focused on the relationship between positive economic endeavors and environmental pollution. Furthermore, the study recommends that while framing a trade policy, its possible impact on environmental pollution also needs to be considered.

Growth Indicators

Based on the Environmental Kuznets Curve hypothesis (EKC), the measurement models of various environmental pollution indicators with economic growth indicators were obtained by using the regression simulation of PASW Statistics 18.0 statistical software based on the data of environmental indicators and economic growth indicators in Jilin Province, and analyzed the characteristics of EKC. The result indicated that the EKC of environmental indicators did not completely accord with the “U” shape. The EKC of industrial wastewater discharge amount showed the “U + inverted U” shape, the inflection point appeared in 2009; The EKC of industrial waste gas emissions was in continuous growth without an inflection point; The EKC of industrial solid waste output showed the left half part of the “U” shape, the inflection point will appear in 2014. The EKC of industrial dust emissions was a shape of logarithmic function, being in a gradually decreasing trend without an inflection point; The EKC of industrial SO2 emissions showed the “U + inverted U” shape, the inflection point appeared in 2008; The EKC of COD discharge amount of industrial wastewater showed the unobvious “U + inverted U” shape, the inflection point appeared in 2009. The overall environmental pollution level in Jilin Province was in the stage of continuous improvement.

Abstract The development of digital economy affects environmental pollution emission and green sustainable development. However, the relationship between digital economy and industrial wastewater discharge has rarely been examined. This study establishes the urban digital economy evaluation index system, measures the digital economy indexes of 281 prefecture-level cities in China from 2011 to 2016, and examines the impact effect of digital economy development on industrial wastewater discharge using the system generalized method of moment method and the intermediary effects model. The empirical results indicate that the digital economy reduces the industrial wastewater discharge. As evidence shows, the digital economy significantly promotes the upgrading of industrial structure, which is an important factor affecting the industrial wastewater discharge. Additionally, the inhibiting effect of digital economy on industrial wastewater discharge is more significant in big cities. This study provides a scientific base and guidance for reducing environmental pollution emissions and promoting the development of digital economy.

The Impact

A rational approach for the design of the activated sludge process based on wastewater and biomass characterization techniques as applied to the upgrading of the treatment plant of Volos, a city in the central part of Greece, is presented. The study investigates possible nitrification inhibition and carbon inadequacy, due to high salinity, industrial inflows and pre-precipitation by iron salts. The experimentation was carried out by means of batch Ammonium Uptake Rate (AUR) and Nitrates Uptake Rate (NUR) tests. The results show that within the studied range, 900-4000 mg l−1, chlorides did not inhibit nitrification. Contrary to this, the industrial wastewater entering the plant was found to be toxic. With the existing 1:15 ratio of industrial to total wastewater flow a 50% inhibition to the nitrification process was observed, which is higher than the 25 - 30% inhibition caused by typical domestic sewage. Industrial contributions exceeding 20% resulted in complete inhibition of nitrification. With respect to denitrification it was found that the industrial wastewater provided a suitable source of carbon, without any adverse effects on denitrification. Pre-precipitation removed about 25% of the filtered COD, thus reducing the amount of nitrates which could be rapidly denitrified. Design of the biological reactors on the basis of the findings indicate that a significant under-design may result if typical nitrification and denitrification rates obtained from the literature and practice concerning typical domestic sewage are adopted.

The purpose of this study is to evaluate the impact of public investment programs on the socio-economic development of territories. As a case, the federal target programs for the development of regions and investment programs of the financial development institution — Vnesheconombank, designed to solve the problems of regional development are considered. The impact of the public interventions were evaluated by the “difference in differences” method using Bayesian modeling. The results of the evaluation suggest the positive impact of federal target programs on the total factor productivity of regions and on innovation; and that regional investment programs of Vnesheconombank are improving the export activity. All of the investments considered are likely to have contributed to the reduction of unemployment, but their implementation has been accompanied by an increase in social inequality.

As 21st century is the era of modern technologies with different aspects, it offers us to make the best use of them. After tape recorder and overhead projector (OHP), multimedia has become an important part of language classroom facilities for its unique and effective application in delivering and learning lesson. Although in many parts of Bangladesh, a South Asian developing country, where English enjoys the status of a foreign language, the use of multimedia in teaching and learning is viewed as a matter of luxury. However, nowadays the usefulness and the necessity of it are well recognized by the academics as well as the government. The study aims to focus on the difference between a traditional classroom void of multimedia and multimedia equipped classrooms at university level by explaining how multimedia support the students with enhanced opportunity to interact with diverse texts that give them more in-depth comprehension of the subject. It also focuses on audio-visual advantage of multimedia on the students’ English language learning. The study has followed a qualitative method to get an in-depth understanding of the impact of using multimedia in an English language classroom at tertiary level. For this purpose, the data have been collected from two different sources. Firstly, from students’ written response to  an open ended question as to their comparative experience of learning  lessons with and without multimedia facilities; and secondly, through  observation of English language classes at a private university of Dhaka, the capital city of Bangladesh. The discussion of the study is limited to  the use of multimedia in English language classroom using cartoons, images and music with a view to enhance students’ skills in academic writing, critical analysis of image and critical appreciation of music. For this purpose, cartoons in English language, images from Google and music from You Tube have got focused discussion in this paper.

The Impact

One of the obstacles in project construction is that the project is experiencing delays. The delay is influenced by several factors including the absence of risk recording, the unavoidability of the opportunities and the impact of risks that arise in the project and its handling, and the neglected risks that may disrupt the project. Project risk is the cumulative effect of an uncertain event opportunity, which affects the project objectives. Several methods can be used to handle the occurrence of project risk, one of the methods used to perform a risk assessment is the Probability Impact Matrix (PIM). PIM is a method that can be used to analyze risk qualitatively based on probability and its impact. By using the PIM method, some of the opportunities and impacts of risks that may arise in the project can be identified. In addition, the PIM method can minimize the risks that arise in the project and quickly resolve the risks. Index Terms— Project, Risk, PIM, Possibility, Impact
