Although Freud's ‘Family Romances’ from 1909 is hardly ever discussed at length in secondary literature, this article highlights this short essay as an important and informative text about Freud's changing perspectives on sexuality in the period in which the text was written. Given the fact that Freud, in his 1905 Three Essays, develops a radical theory of infantile sexuality as polymorphously perverse and as autoerotic pleasure, we argue that ‘Family Romances’, together with the closely related essay on infantile sexual theories (1908), paves the way for new theories of sexuality defined in terms of object relations informed by knowledge of sexual difference. ‘Family Romances’, in other words, preludes the introduction of the Oedipus complex, but also – interestingly – gives room for a Jungian view of sexuality and sexual phantasy. ‘Family Romances’ is thus a good illustration of the complex way in which Freud's theories of sexuality developed through time.

We consider the tail behavior of the product of two independent nonnegative random variables X and Y. Breiman (1965) has considered this problem, assuming that X is regularly varying with index α and that E{Yα+ε} < ∞ for some ε > 0. We investigate when the condition on Y can be weakened and apply our findings to analyze a class of random difference equations.

A Rao–Nam cryptosystem based on error correction code is proposed to provide both security and reliability. Since its security is drastically constrained by the limited error syndromes, in this paper, an improved Rao–Nam cryptosystem based on fractional order hyperchaotic system and Extended Difference Family–Quasi-Cyclic–Low-Density Parity-Check (EDF–QC–LDPC) codes is proposed to improve the security. A four-dimensional fractional order hyperchaotic system is constructed and is used to generate an excellent pseudorandom sequence. By replacing error syndromes with the pseudorandom sequence and permuting the coded message dynamically, the security of the Rao–Nam cryptosystem is enhanced greatly. The ability of the improved Rao–Nam cryptosystem against known attacks is analyzed and the error correction performance with different parameters is simulated. The results show that the proposed cryptosystem has a significant advantage of resisting the chosen-plaintext attack. Moreover, the proposed cryptosystem retains high capacity of error correction.

We relate the equilibrium size of an M/M/8 type queue having an intermittent arrival stream to a perpetuity, the solution of a random difference equation. One consequence is a classical result for ranked server systems, previously obtained by generating function methods.
