A new method for non-parametric multivariate analysis of variance in ecology

, 2001
Hypothesis-testing methods for multivariate data are needed to make rigorous probability statements about the effects of factors and their interactions in experiments. Analysis of variance is particularly powerful for the analysis of univariate data. The

pollution-intensive sectors of the economy to the cleaner sectors. The comparative advantage of the former is diminished by such a policy. Thus, environmental legislation affects the international division of labour and can be used to achieve trade-policy objectives. This is particularly appealing if the traditional instruments of trade policy, tariffs

Ecological discounting [PDF]

open access: possibleJournal of Economic Theory, 2010
Which rates should we use to discount costs and benefits of different natures at different time horizons? We answer this question by considering a representative agent consuming two goods whose availability evolves over time in a stochastic way. We extend the Ramsey rule by taking into account the degree of substitutability between the two goods and of

Toward an Experimental Ecology of Human Development.

, 1977
A broader approach to research in hu- j man development is proposed that focuses on the pro- \ gressive accommodation, throughout the life span, between the growing human organism and the changing environments in which it actually lives and grows.

Parasitology meets ecology on its own terms: Margolis et al. revisited.

Journal of Parasitology, 1997
We consider 27 population and community terms used frequently by parasitologists when describing the ecology of parasites. We provide suggestions for various terms in an attempt to foster consistent use and to make terms used in parasite ecology easier ...

Ecological Validity and “Ecological Validity”

Perspectives on Psychological Science, 2021
Egon Brunswik coined the term ecological validity to refer to the correlation between perceptual cues and the states and traits of a stimulus. Martin Orne adapted the term to refer to the generalization of experimental findings to the real world outside the laboratory. Both are legitimate uses of the term because the ecological validity of the cues in
