Theories of human color constancy have been based on experiments with relatively simple laboratory stimuli. Even recent “nearly natural” stimuli are optically much simpler than natural visual environments. I review here some of the complexity of natural visual environments. I argue that several kinds of optical structure exploited by theories of human color constancy may not occur in most natur...

The major goal of this paper is to point out the frontiers of environmental chemistry and the new paradigms for the next decade, with especial focus to Latin America countries. To better address the issue, three different scenarios were selected: (a) major changes in laboratory routine and research activities; (b) extra-laboratory tendencies; and (c ) legal, political and social aspects. In the...

Environmental psychology is the subdiscipline of psychological science that deals with psychological processes engaged in encounters between people and the built and natural environment (Stern, 2000). It covers all aspects of human behavior and mental life in relation to the sociophysical environment, whether considered as ambient environmental factors (e.g. infrastructure of everyday life (e.g...

We live in an era of environmental deterioration through depletion and degradation of resources such as air, water, and soil; the destruction of ecosystems and the extinction of wildlife (Kondratyev, 1998; Kondratyev et al., 2004; Cracknell et al., 2009; Hansen et al., 2013; Freedman, 2014). As a matter of fact, environmental degradation is one of three main threats identified in 2004 by the Hi...

Epidemiology is struggling increasingly with problems with correlated exposures and small relative risks. As a consequence, some scholars have strongly emphasized molecular epidemiology, whereas others have argued for the importance of the population context and the reintegration of epidemiology into public health. Environmental epidemiology has several unique features that make these debates e...
