Tobacco use adversely affects many aspects of well-being and is disliked by non-smokers. However, its association with family happiness is unknown. We investigated the associations of family unhappiness with smoking in family members and secondhand smoke (SHS) exposure at home in Hong Kong children. In a school-based survey in 2012-2013, 1238 primary school students (mean age 8.5 years, standar...

If environmental quality positively a ects the productivity of labor in R&D and pollution is caused by the use of a non-renewable resource, it is socially optimal to postpone extraction and to intertemporally adjust R&D e ort.

We consider the problem of regulating an economy with environmental pollution. We examine the distributional impact of the polluter-pays principle which requires that any agent compensates all other agents for the damages caused by his or her (pollution) emissions. With constant marginal damages we show that regulation via the polluter-pays principle leads to the unique welfare distribution tha...

On the base of the residential interior decoration and the air pollution status in China, as the requirements of indoor air quality at present are increasing, from the concept of healthy house, new idea is proposed that indoor air pollution is controlled by overall process through green interior design, selecting environmentally friendly materials and green decoration for safety, healthy and en...

In high frequency signal packaging, the plastic dielectric material takes on an increasingly important role in the performance of the signal transmission. Variations within the plastic can occur as a result of a number of manufacturing and environmental processes. These variations can be sufficient to change the dielectric properties. The extent of change to the dielectric properties of polymer...

Making use of concrete materials in cut-off walls, because of their low permeability and standing high Hydraulic Gradient caused by underground drainage, has attracted great amount of attention. Using ordinary concrete with high elasticity modulus, compared to other materials may accompany with problems including brittleness of cutoffs due to dynamic stresses. To solve this problem, adding a ce...

The whole world today is facing an enormous increase in plastic waste pollution caused by the emergence of COVID – 19 pandemic. A complex chemical composition personal protective equipment (PPE) mainly containing polypropylene (PP) complicates recycling process and it could take at least 450 years to degrade. Plastic was already one greatest threats our planet before coronavirus outbreak. Dispo...

When economic activity leads to pollution and over-use of common property resources, government intervention can improve social welfare. Pollution involves a market failure in which damages caused by a producer or consumer are imposed on third parties. These damages can involve personal health, physical deterioration of buildings, and foregone options for the future. Of course, if transactions ...

Environmental monitoring is required to understand the effects of various kinds of phenomena such as a flood, a typhoon, or a forest fire. To detect the environmental conditions in remote places, monitoring applications employ the sensor networks to detect conditions, context models to understand phenomena, and computing technology to process the large volumes of data. In this paper, we present...
