How can the classical psychological laws be explained and unified? It is proposed here that scale-invariance is a unifying principle. Distributions of many environmental magnitudes are observed to be scale invariant; that is, the statistical structure of the world remains the same at different measurement scales [Mandelbrot, B., 1982. The Fractal Geometry of Nature (2nd Edn.). W.H. Freeman, San...

In continuing news, there is a growing debate on whether current laws and regulations, both in the US and abroad, need to be strengthened as they relate to nanotechnology. On one side, experts argue that nanomaterials, which are making their way into the marketplace today, are possibly harmful to consumers and the environment, so stronger and new laws are needed to ensure they are safe.

BACKGROUND Children younger than 72 months are most at risk of environmental exposure to lead from ingestion through normal mouthing behavior. Young children are more vulnerable to lead poisoning than adults because lead is absorbed more readily in a child's gastrointestinal tract. Our focus in this study was to determine the extent to which state mandated lead laws have helped decrease the num...

There is growing concern, however, about the environmental consequences of increased international trade. Typically, different countries have different environmental regulations and it is argued that the developed countries have more stringent en...

Environmental management system (EMS) comprises of management practices that helps an organization to assess their level of efficiencies in meeting the environmental responsibilities. EMS involves listing of all environmental legislations, all environmental effects associated with activities, setting targets, keeping appropriate records and undertaking regular reviews of organization for sound ...

achieving effective environmental policy making and environmental protection. Its particular focus is on toxic substances and chemical hazards. It asserts that the community is a major stakeholder in respect of environmental policy, and it argues that access to information is an essential prerequisite for effective community input into environmental decision-making. More specifically, informati...

A cursory examination of the legal environmental systems of some developing countries lends credibility to the argument that nation states, particularly those of the developing world, cannot be relied upon to pursue environmental objectives beneficial to the global commons. The results of some country studies, for example, Mexico, Chile, and Brazil take this position. R. Findley, in his study o...
