Color Plate 11-11 shows an image lit with a total of five spotlights, two from above and three from below. In the first example, I left the Texture Channel option set to None. In the second example, I selected the green channel as the surface map. And in the third example, I filled a separate mask channel with a bunch of white and black dollops using Filter Pixelate Pointillize and then I selected the mask from the Texture Channel pop-up menu in the Lighting Effects dialog box. The result is a wonderfully rough paper texture.

Risk analysis has been used widely in the appraisal of capital works and in the comparative assessment of available options, as discussed in previous chapters. The remainder of this chapter is concerned with the contribution of risk analysis to the economic appraisal process. Common approaches to taking risk and uncertainty into account in the cost-benefit process include: sensitivity analysis, including determining the effect of plausible changes in uncertain parameters on decision criteria such as NPV or ROR; loading the discount rate by adding a risk premium;

Global Concerns These environmental problems have adverse impacts that are felt far beyond the location where environmental mismanagement occurs Their effects are transnational and can even threaten the very survival of global ecosystem in the long term Issues such as global warming or the stratospheric ozone layer depletion fall into this category Addressing problems in this category is complicated by the fact that the multiple perpetrators (or the polluters) are not always readily discernible Resolution of these requires an international effort, nations acting in concert toward a common goal to ensure the rights of future generations Local and Regional Concerns The more familiar environmental problems have to do with local or regional impacts of pollution such as the release of toxic chemicals into the environment, management of municipal solid wastes, or the disposal of spent nuclear fuel.
