Accelerated degradation of municipal refuse in modulated landfill environments may alleviate or eliminate pollution to the land, water and air. In this work, nineteen effective microorganisms (EMs) were isolated from old landfill refuse by enrichment culturing techniques and used for the inoculum of municipal refuse. The preliminary experiments demonstrate that a combination of EMs inoculation in landfill with leachate recycle resulted in increased rates of decomposition and faster process stability. The concentrations of COD, VFA and SO4^2- in digester with EMs inoculation and leachate recycle decreased more rapidly than others. Gas production from digester with EMs inoculation and leachate recycle commenced around 32 days, which is a week shorter than with leachate recycle only. And peak cumulative gas production was obtained much earlier in digester with EMs inoculation and leachate recycle (150 days) compared to 180 days with leachate recycle only. Moreover, in the first two months, the rate of settlement in digester with EMs inoculation and leachate recycle was more rapid than others.展开更多

From that time, all types of shopping centres were built, starting from the very basic first generation and developing into the most current formats. In the article, types of shopping centres are compared to their western origins. Planning laws and procedures that apply to the processes are also described, with an example of a law that was introduced to specifically control growth of shopping centres. Apart from that current trends and growth possibilities in the present market situation are discussed. As a result, a very rapid development process was observed, with little hampering from the planning policies. This may be used as a point of reference for other countries that have not yet encountered that process.展开更多

Stratified sampling and typical case study were adopted and 236 questionnaires were collected from four vil- lages, Daxin, Lixin, Longhe and Yongchang. We analyzed the rural-urban migration rate, household income and local geographical factors, focusing on the ratio of remittance income to total household income. Data descriptions and sta- tistical methods, such as Pearson Chi-square test, Contingency coefficient, Eta, Pearson correlation coefficient, t-test, multiple comparisons (LSD test, Tamhane T2, Dunnett T3 and Dunnet C test) were used. The results are as follows. Rural households’ income is diversified in survey villages so the motivation of rural-urban migration in the study area can be partly explained by NELM. The migration rate of households (the percentage of households with migrants in survey households) in survey villages varies from 50% to 86%, while the proportion of remittance income to house- hold income is in the range of 30% to 80%. In the village of Yongchang, with the least average arable land area per household, the remittance income plays a vital role in household income (80%). And the statistical findings show that the proportion is significantly and negatively correlated with arable land area per household. The conclusion is that di- rect effect of migration, i.e., the contribution of remittance to household income, is negatively correlated with the con- tribution of resources to local income.展开更多

However this achievement is still be overshadowed by the harvesting method which is conventional and labor intensive. An attempt to use mechanization into the harvesting system, in particular the cutting process of tall palm trees, has been unsuccessful. At the beginning of the oil palm's fruit bearing fife, i.e. 3 to 4 years of age, fi'uit bunches are still accessible. For these palms, a chisel is used to cut the fiuit bunches. Growth is such 8-10 years, and the trees have already reached substantial height. In these cases a sickle mountedon flexible telescopic aluminum tube (pole) is used. This, however, exposes plantation worker to the risk of musculoskeletal discomfort and injury. This paper examines the problems by assessing the task posture and tool, and their implications for operators, using questionnaire survey and videotape analysis techniques. The result prevails that there is evidence to associate the problems of musculoskeletal disorders among the operators.展开更多

It was based on income taxes and turnover (especially value added) taxes. Primarily income taxes had high tax rates. In corporate tax the rate was proportional and at the beginning amounted to 40%. For natural persons the taxation had a progressive tendency. The tax rates amounted to 21%, 33% and 45% respectively with very low limits of income, which resulted in changing the rate. Since the beginning of 1991 and 1992 till now the tax rates have been decreased significantly. Now the tax rates amount to 18% and 32% respectively with high level of income, which results in changing the rate. The question arises whether such changes were really effective for the central budget. The article formulates and verifies a hypothesis assuming that lowering the rates was justified by the contemporary "fashion" rather than economic reasons. According to financial aspects, the impact of lower rates on the central budged will be examined.展开更多

We conclude that it is an indispensible strategy to give priority to the development of urban sectors to promote economic growth and reduce rural poverty, and that the development of low value-added agriculture yields few, if any, benefits in decreasing rural poverty. By first adopting urban-biased policies and promoting industrialization, China has created new sources of economic growth and urban employment opportunities to absorb the surplus rural workforce. Entering labor-intensive industrial sectors for higher incomes has thus become a critical avenue for the rural poor to benefit from economic growth and escape poverty.展开更多

The construction principles and advantages of the SNCM method are proposed and the method tested in Wanyuan city of Qinba Mountain area(Southwest China) to verify its feasibility and optimization. Taking account of the mountain terrain and its influence on user behavior, we used the SNCM method to build a comprehensive model which integrates the road slope and the walking speed of pupils into the basic spatial model. The model is used to calculate a reasonable layout of the primary schools and to validate the rationale. The results show that the SNCM method can be effectively applied in low-income mountainous cities. It can not only improve the accessibility and service efficiency of primary schools using as little capital-investment as possible, but also help the city grow in an intensive and efficient way.展开更多

Recent technological advances and trade liberalization have made India a major player in international cotton markets. In the year 2011-2012, India was the world's second largest producer, consumer and exporter of cotton. The increasing role of the Indian cotton sector in international markets is a direct challenge to other major players like the US. Within this context, a better understanding of the Indian cotton sector and the impact of mechanization on cotton cultivation are needed. The overall objective of this paper is to assess the competitiveness of Indian cotton producers and potential implications for India as a competitor in the world cotton market if it mechanizes harvesting of cotton. The results demonstrate that the net income of the Indian cotton farmers will increase considerably with the mechanization of cotton harvesting. But the adoption of the practice of harvesting cotton by mechanical means is possible only if efforts from many private and public agencies come together. In that scenario, the cotton production in India can increase considerably which can impact the international markets.展开更多

The possibility to introduce in the Italian context the DMS (direct melting system) technology, designed and manufactured by Nippon Steel Engineering Co. Ltd., has been taken into account for the scope of proposed work. DMS technology consists in MSW gasification, slags melting and combustion of the syngas produced, with the consequent generation of electric energy through a steam cycle. The system minimizes environmental impact, thanks to an effective recycling of useful resources such as inert melted slags and metals, featuring high flexibility in terms of treatment capacity due to its modular design. The aim of this article is to consider different plant configurations in order to optimize the energy recovery downstream the DMS module. As a case study, landfill gas exploitation integrated in the DMS plant will be considered as a typical situation that could occur in the Italian scenario. The energetic input provided by the biogas allows improving the thermo-economic performances according to market incentives.展开更多

A major problem in the city of Tshwane is that all the MSW generated in the city is currently being landfilled with very little recycling initiatives. Selective waste collection and sorting waste fractions out of the waste stream have become a popular survival strategy for the economically excluded population in Tshwane. Reclaimers (waste pickers) work under severe and chronic occupational health and injury risk on landfill sites. The middlemen who purchase their recovered materials exploit and marginalize them. Environmental and social awareness is however a growing issue in South Africa. The study was conducted with the aim of investigating and proposing community recycling programs and technologies to be sustainably implemented in the city of Tshwane. Successful established community recycling programs in Brazil was investigated to verify its socioeconomic and environmental impacts in a sustainable waste management perspective. Community recycling initiatives have been increasingly used as a strategy to address both the MSW problem and urban poverty in Brazil. The study focused on the city of Tshwane, but it can be argued that the findings can be implemented in any other South African municipality and in other emerging countries in Africa.展开更多

Taxation as an important means of macroeconomic control the government, has a unique role to adjust income distribution and narrow the income gap. Taxation can not be replaced by other policies, the development of which has been confirmed by the practice in developed market economies of Western countries. In order to improve the distribution of income inequality in our country, we need to regulate the initial distribution and redistribution. Therefore, limiting public power, strengthening monopoly regulation and standardizing the labor market are the key, while the macro-control means, such as taxes, transfer payments and social security should be widely adopted. Practice during our transition period shows that adjusting personal income distribution through the tax system is an important part of the government's public policy, but also an objective requirement of building a socialist harmonious society.展开更多

As a result, a reasonable prediction of asset-expected future returns has become one of the core contents of the income approach. The forecast on expected future earnings is generally based on many uncertain factors, such as strict conditions of assumption and the complexity of environment. However, the current valuation practice in this aspect varies greatly and sometimes depends on personally experienced judgment of appraisers. Therefore, the obtained valuation results tend to be simplified and absolutized. This paper takes a listed company in China as an example to explore the way of inserting an uncertainty analysis into the prediction of the income approach, and then to obtain a series of valuation results within a certain probability fluctuation range. Finally, it puts forward some suggestions about the Monte Carlo simulation (MCS).展开更多

If the capital market is competitive, the investors cannot expect superior gains from their investment strategies with respect to the risk profile. Event studies are an approach to verify the impact of the information on the stock prices. In an efficient market, stock prices should fully, promptly, and quickly capture all the information. Instead, the market shows phenomena of an under-reaction and over-reaction for both the short and the long run. The mergers and acquisitions (M&As) are examples of anomalies. Often, the bidder companies record the negative abnormal returns for both the short and the long run. In contrast to the efficient market theory, the empirical evidence shows that this phenomenon is widespread in all (or most of) the countries of the world. This work examines the long-run performance in M&As. For this purpose, 40 bidders were observed in Italy during the period of 1994-2008 among listed companies. The buy and hold abnormal returns (BHARs) methodology was used, with which it was possible to observe the returns for three years following the deal.展开更多

This qualitative study aimed at establishing reasons as to why there was still improper solid waste management in Mbarara municipality and also establishing its constraints. Tools used included semi-structured questionnaires, observation and photographs. Two hundred and ninety-four participants (24 solid waste collectors, eight municipal council members and 262 community members) participated in the study. The study revealed both insufficient budget (87.5%) and insufficient equipment (50%) as the most common policy challenges in implementing proper solid waste management. Solid waste collectors not being comfortable with their salaries (79.2%), limited sensitization regarding solid waste management (66%) and limited necessary tools (58.3%) as other challenges faced by solid waste management policy makers and implementers and finally, community members having limited awareness about laws governing solid waste management (61.1%). In conclusion, insufficient budget, insufficient equipment, poor motivation and inadequate sensitization were found to be the major reasons as to why there was still improper solid waste management in Mbarara municipality, western Uganda.展开更多
