The Case for Improving U.S. Computer Science Education

Despite the growing use of computers and software in every facet of our economy, not until recently has computer science education begun to gain traction in American school systems. The current focus on improving science, technology, engineering, and mathematics (STEM) education in the U.S. school system has disregarded differences within STEM fields. Indeed, the most important STEM field for a modern economy is not only one that is not represented by its own initial in "STEM" but also the field with the fewest number of high school students taking its classes and by far has the most room for improvement—computer science

Economic Doctrines and Approaches to Climate Change Policy

In climate change, as in all policy issues, economic philosophy has a significant influence on how people view both the problems and the solutions. For the first time, ITIF surveys four dominant schools of economic thought and analyzes how adherents approach policy options for climate change and energy policy. With climate change and major energy legislation stalled, maybe it is time to put aside fixed philosophical notions and take a practical look on ways to address climate change in an economically feasible way. The report reviews the principles and goals of each economic doctrine, and offers a critique of the advantages and limitations of each doctrine's contribution to addressing the challenge of climate change.Innovation; Economics; Climate Change; Public Policy

The enumeration of three pattern classes using monotone grid classes

The structure of the three pattern classes defined by the sets of forbidden permutations \{2143,4321\}, \{2143,4312\} and \{1324,4312\} is determined using the machinery of monotone grid classes. This allows the permutations in these classes to be described in terms of simple diagrams and regular languages and, using this, the rational generating functions which enumerate these classes are determined

The enumeration of permutations avoiding 2143 and 4231

We enumerate the pattern class Av(2143, 4231) and completely describe its permutations. The main tools are simple permutations and monotone grid classes

Permutation Classes of Polynomial Growth

A pattern class is a set of permutations closed under the formation of subpermutations. Such classes can be characterised as those permutations not involving a particular set of forbidden permutations. A simple collection of necessary and sufficient conditions on sets of forbidden permutations which ensure that the associated pattern class is of polynomial growth is determined. A catalogue of all such sets of forbidden permutations having three or fewer elements is provided together with bounds on the degrees of the associated enumerating polynomials.Comment: 17 pages, 4 figure

Small Business Incubators: A Tool for Economic Development

This article describes how incubators can help small businesses. It examines and presents examples of four types of facilities in the United States. The author addresses the question of how the effectiveness of incubators can be evaluated and concludes by discussing the North Carolina Incubator Facilities Program
