In this meaning, I present some points in the Theory that was or still are focus of Academic debates. I discuss general aspects related to the context of the cited Theory quoting Academic Physics’ behavior. I also quote some scientists with opposite position to this Theory with approximately 3800 documents whose sources are cited therein. I present some tests such as the Liar Paradox and the impact of Einstein’s Theory of Relativity. Aiming at the better understanding and analysis I present, too, some Reception Studies of this Theory in the European latin languages countries such as France, Italy and Spain. Portugal was excluded because of the lack of significative informations. Some information about Germany, England and the United States are inserted in the work to the better understanding of the facts about the reception studies. The main conclusion of the paper is that Einstein plagiarized Langevin.

Some of these critics were cited in the present work, as well as other related to the procedure of hypothesis selection. Therefore, basic concepts about the subject are initially presented to the reader, as the Law and the Principle of likelihood, the Irrelevance of the Sample Space and the Law of Improbability. After this, the significance tests are exposed and the conclusion points to the need of the actualization of the didactic material of the statistics disciplines as well as the curriculum of the courses that contains this discipline.

Environmental management with focus in the sustainability and with attention to the ecological footprint is an alternative to minimize the overload that natural systems has been subjected to and also generating gains for the organizations. Despite cities are naturally unsustainable, from the vertebrate fauna list of Porto Alegre there were identified candidate species to key-species that must be preserved in the areas were the ecological footprint is reduced and with focus in their conservation.

The results of this survey were compared with specialized references of the epidemiological area, of the infectious and parasitic diseases, and about venomous animals for the identification of possible disease vectors. Several species of Insecta and Arachnidae, as well as some Mollusca species, were identified with this procedure.

It is a model developed over a cellular automata background and it is grounded in published scientifical studies that consider ecological and physiological features. The results of this model configure acceptable biological behaviours. The resilience analysis that aims in the determination of the exploration consequences shows that the increase of the extraction rate causes increased times for the virtual community restoration. This analysis also shows that this increase is related to the increase on the extinction probability of any ecophysiological type present in the community. Consequently, it is demonstrated that to have any sustainable exploitation of the natural resources the extraction level can not cause the extinction of any resource.

Applied in the context of ecosystems, the model allows the study of a different amount of species, defined each as an ecophysiological type, such as a bush, a canopy tree and an emergent tree. The study presented relies in a resilience analysis of the communities developed with CAVeg. Showing that as the complexity of the system increases the system demands more time to restore to a similar previous condition, the study suggests that, in a similar manner, as the complexity of the system increases and as the exploitation interval increases, a quadratic fit with two ecophysiological types rises to a linear fit with three ecophysiological types, being expected an exponential regression fit for communities with more ecophysiological types. The CAVeg model references that support the model are presented therein and biological acceptable behaviours were observed.

The approach is validated through comparisons of model results with available data. The model which validates the approach reproduces observed data without statistical difference from another model developed with Markov chains from the same data. Another model developed to analyze the consequences of exploration is based in published scientific studies. The scientific studies on which the model is based consider ecological and physiological aspects. The results of this model show biologically acceptable behaviors. The resilience analysis, which seeks to determine the consequences of the exploration, shows that increases in the extraction rate result in higher restoration times for the
virtual community and in higher extinction probabilities for some ecophysiological type in the community. Consequently, it is shown that the extraction rate of an exploration of a natural resource, to be sustainable, must not result the extinction of any resource. Additionally, it is recommended that experiments be conduced in small scale before proceeding with large scale exploration. It is also shown that there are differences between populations in equilibrium in spatial models and in equilibrium in their non-spatial analogues. The implications reside on the natural reserves management and on the application of the maximum sustainable yield, especially when practiced upon species almost extinct.

The model can simulate community composition and spatial patterns by following a set of probabilistic rules generated from empirical data on plant neighborhood dynamics. Based on published data , we apply the model to simulate Atlantic Heathland vegetation dynamics and compare the outcome with previous models described for the same site. Our results indicate reasonable agreement between simulated and real data and with previous models based on Markov chains or on mechanistic spatial simulation, and that spatial models may detect similar species dynamics given by non-spatial models. We found evidence that a directional vegetation dynamics may not correspond to a monotonic increase in community spatial organization. The model framework may as well be applied to other systems.

Hierarquical representation is indicated for interpretation category expert systems that deal with classification, and may be used in land use determination systems such as the American and Brazilian. Introspection eases initial development of an expert system in cases where information for state definitions is found in the classification system itself, as in the D’Agostini & Schlindwein (1998) evaluation system. Object-oriented programming concepts are applied to system development.

The model can simulate community composition and spatial patterns by following a set of probabilistic rules generated from empirical data on plant neighborhood dynamics. Based on published data (Lippe et al. 1985), we apply the model to simulate Atlantic Heathland vegetation dynamics and compare the outcome with previous models described for the same site. Our results indicate reasonable agreement between simulated and real data and with previous models based on Markov chains or on mechanistic spatial simulation, and that spatial models may detect similar species dynamics given by non-spatial models.
