Stochastics theory of log-periodic patterns

We introduce an analytical model based on birth-death clustering processes to help understanding the empirical log-periodic corrections to power-law scaling and the finite-time singularity as reported in several domains including rupture, earthquakes, world population and financial systems. In our stochastics theory log-periodicities are a consequence of transient clusters induced by an entropy-like term that may reflect the amount of cooperative information carried by the state of a large system of different species. The clustering completion rates for the system are assumed to be given by a simple linear death process. The singularity at t_{o} is derived in terms of birth-death clustering coefficients.Comment: LaTeX, 1 ps figure - To appear J. Phys. A: Math & Ge

Anonymous Women? A Scoping Review of the Experiences of Women in Gamblers Anonymous (GA)

Women are participating in gambling at levels approaching those of men, and although levels of disordered gambling remain lower in women than in men, significant numbers are affected. Gamblers Anonymous (GA) is a mainstay of help to problem gamblers in many countries. A scoping review was conducted which specifically addressed the experiences of women who attend GA. Within the 25 identified relevant studies, only two reported empirical data on the specific numbers of women attending. A range of barriers still remain to the participation of women in these communities. These include ‘external’ barriers such as lack of referral and signposting, lack of accessible meetings, and costs of travel; ‘internal’ barriers such as shame, stigma, and fear of disclosure; and features of the GA meetings and discourse, such as a climate which is dismissive of women’s experiences
