The R7RS (small) language standard can be implemented while preserving near-perfect backward compatibility with the R6RS standard and substantial compatibility with the R5RS and IEEE/ANSI standards for the Scheme programming language. When this is done, as in Larceny, R6RS Scheme becomes a proper subset of R7RS Scheme.

In this study, we use county data on private security establishments and employment for 1977–92 to test two hypotheses. First, we test whether private security deters crime.
