Causes of Large-Scale Native American Deaths Between 1500 and 1700 Between 1500 and 1700‚ most of the original Native American population vanished. After European conquest‚ the ways of living for the Native Americans had forever changed‚ and few had survived large-scale deaths to carry on or learn to live in harmony with the Europeans. Deaths in such great numbers did not result from a single cause. Rather it was a combination of many different causes that led to a near extinction of the Native

“Empiricism‚ Semantics and Ontology” by Rudolf Carnap I. The Problem of Abstract Entities Empiricists attempt to limit themselves to nominalistic language‚ a language not containing references to abstract entities such as properties‚ classes‚ relations‚ numbers‚ propositions‚ etc. They treat mathematics as a mere calculus wherein no interpretation is given or can be given. However‚ abstract entities are impossible to avoid for some scientific contexts. The theory of meaning and truth is the problem

In behavior modification‚ differential reinforcement is referred to as rewarding only the desired responses/behaviors; meaning that all other behaviors and responses are ignored. For instance‚ when a child throws a tantrum at the supermarket‚ demanding for a candy bar‚ his parent can choose to ignore this behavior instead of reacting to it. As this attention may be perceived as rewarding to the child. At the point when the child understands that having a tantrum results in a non-response from his
