Determinants of OSS revenue model choices

The open source software movement is traditionally not affiliated to profit-oriented business behaviour. However, commercial activity has become increasingly common, and, business models have institutionalized in the field of open source software. The aim of this research paper is to explore the determinants of profitable revenue models for businesses based on open source software. Therefore, t...

Determinants of Recent Immigrants’ Locational Choices

High levels of immigration to the United States have caused the size of the foreign-born population to increase dramatically in recent years. Recent immigrants are concentrated in several states, particularly California. This paper examines the determinants of the intended state of residence of new recipients of legal permanent-resident status and new refugees over the 1989–94 period. The prese...

Determinants of Voluntary Accounting Policy Choices by Australian Life Insurers

This paper empirically examines various incentives facing managers of Australian life insurers to voluntarily use actuarial-based income smoothing techniques (AIS). AIS were subsequently incorporated into jointly-developed Australian and New Zealand life insurance accounting standards (LIAS) issued in 1997. The propensity of managers to voluntarily use AIS is predicted to be related to the firm...

Combinatorics Enumerative Combinatorics 05

Analytic Combinatorics — Symbolic Combinatorics

This booklet develops in nearly 200 pages the basics of combinatorial enumeration through an approach that revolves around generating functions. The major objects of interest here are words, trees, graphs, and permutations, which surface recurrently in all areas of discrete mathematics. The text presents the core of the theory with chapters on unlabelled enumeration and ordinary generating func...
