The microplate reader is a multimodal instrument that allows for a variety of experiments to be performed and measured simultaneously. Microplate readers can make absorbance, fluorescence and luminescence measurements. Multiwell plates are integral to the microplate reader and allow for many experiments to be performed at once. Regardless of the assay type, experiments on the plate reader utilize a standard curve to determine the experimental values. This curve uses samples of known...

The Edgeworth Box, introduced by Francis Edgeworth, is a graphical tool used to analyze the efficient allocation of resources between two entities, such as consumers or producers. It focuses on the distribution of two goods between two individuals within a controlled framework, offering insights into exchange efficiency and market equilibrium.The box's dimensions are determined by the total quantities of the two goods being analyzed. For instance, if two individuals, Jamie and Morgan, share 12...

The Black Box Model of Consumer Behavior conceptualizes the decision-making process as a "black box" where inputs (stimuli) lead to outputs (responses) without fully revealing the internal cognitive processes. It emphasizes the mystery of the consumer's mind and focuses on observable external factors and responses.
The model includes external stimuli (marketing efforts, social influences), the consumer's black box (psychological factors, perception, and attitudes), and the...

Environmental enrichment provides a potential protective effect against neurodegenerative disorders. Currently, however, there is no easy way of determining the efficacy of enrichment procedures. This protocol describes a simple “Puzzle Box” method for assessing an animal’s cognitive function, in order to reveal the effectiveness of environmental...
