Aritmética de las sucesiones 6n−1,6n+16n - 1, 6n + 1 y de los primos gemelos

This paper considers questions equivalent and similar to those of twin numbers. Two prime numbers are said to be twin if they differ in two units. Except for the pair (3,5), they may be expressed as ($6n-1,6n+1$). The set of the multiples of 6 which separate twin numbers is studied. A theorem of relative density is included ($\S$ 10) as ewll an inductiv process of functional generation of the prime numbers ($\S$ 11)

A million answers to twenty questions: choosing by checklist

Several decision models in marketing science and psychology assume that a consumer chooses by proceeding sequentially through a checklist of desirable properties. These models are contrasted to the utility maximization model of rationality in economics. We show on the contrary that the two approaches are nearly equivalent. Since the number of preference discriminations that an agent can make increases exponentially in the number of properties used, checklists provide a rapid procedural basis for utility maximization
