Recently, plastic bag rubbish has become a problem of concern for researchers in both environmental and economic issues. Results of a survey of 401 households in Cần Thơ city show that most of the respondentss use plastic bags for shopping and containing rubbish. However, about 55% of them are aware of the harm that plastic bags cause for the environment and life. People living in distant and remote areas are much less aware of this sort of harm. Moreover, the burning of rubbish still occurs in the countryside due to the absence of garbage collection. About the issue of waste disposal, the mass media play a more important role in providing perception of the harm from plastic bags than posters or propagandisers.

"The Central Vietnam Key Economic Zone, with its strategically important geographical position, is considered as a zone of great potentials and advantages that will become a dynamic of socio-economic development of Central Vietnam and Western Highlands. This article analyzes its potentials and advantages and identifies barriers to the development of this economic zone, thereby suggesting measures to the exploit such potentials and advantages and remove barriers to the quick and sustainable development of the whole zone. The Central Vietnam Key Economic Zone (hereafter referred to as CVKEZ), established under PM Decision 1085/QĐ-TTg dated 12 Aug. 2008, consists of five administrative units: Thöøa Thieân-Hueá, Đà Nẵng, Quaûng Nam, Quaûng Ngaõi, and Bình Ñònh. Its area, 27,884 km2, accounts for 8.4% of the total area of Vietnam and its population of 6.5 million, accounts for 7% of the total population of Vietnam. It has a string of seven big cities: Hueá, Đà Nẵng, Hoäi An, Tam Kyø, Vaïn Töôøng, Quaûng Ngaõi and Quy Nhôn. Stretching along a coastal line of 609 km are four developing economic zones: Chaân Maây, Chu Lai (an open economic zone), Dung Quaát, and Nhôn Hoäi. Together with this string of industrial zones, export processing zones in this area have the advantage of being near several seaports. The system of national and international warehouses here is to be linked with international ports, and inter-regional and trans-national communications networks. This zone is also very important to national defense, orientation of socioeconomic development of Central Vietnam and Western Highlands, and to the socioeconomic development strategy of the whole country as well. This key economic zone includes marine-based economy associated with industry and services. This zone would develop a pivotal sub-zone that provides spaces for the development of marine-based economy, a coastal corridor for international economic free trade along the national route 1A, the national railway line and the system of seaports. In the development strategy up to 2025, CVKEZ would become the impetus for the socioeconomic development in Central Vietnam and Western Highlands. It is also the chief entrepoât point as well as the center for trade and processing facilities in the greater Mekong area and in the Asia-Pacific rim. "

This study is to investigate the influence of inflation on the effectiveness of the Economic Value Added (EVA) which an investor may employ to quantify the value generated by a company. However, inflation can distort EVA and potentially result in inefficient allocation of resources and policy on rewards. This study will look into the adjusted and nominal EVA in order to measure the business performance as reflected in stock returns, stock market prices and operating cash flows. Some 142 non-financial companies have been invited to join this study and 332 observations were undertaken from 2007 to 2009. The findings have shown that the adjusted EVA seems more sensitive to inflation than the nominal EVA. In other words, the latter is distorted by inflation. Thus, Vietnamese business managers should consider thoroughly before integrating EVA into measuring the business performance, especially when inflation rate has galloped over the past few years.
