'Improper practices' in great war British cinemas

This extract is taken from the author's original manuscript and has not been edited. The definitive, published, version of record is available here: http://www.palgrave.com/products/title.aspx?pid=493370Analysis of the environment in which films were viewed is essential in order to gain a fuller understanding of the British cinema experience during the Great War. The exhibition context is of particular importance during the war years, as cinema going throughout this period was far from idyllic; in fact, British cinemas were subject to police scrutiny and were a hub of sexual activity that the government strove to suppress. Many critics have located the reports of these activities as part of a wider ‘moral panic’ regarding the cinema and the films exhibited within it, predominantly orchestrated by religious pressure groups and self-styled ‘moral crusaders’. Lise Shapiro Sanders likens this movement to similar campaigns in the nineteenth century, arguing that, like music halls previously, cinemas were subjected to ‘censorship and ideological control in an endeavour to distribute middle-class codes of social practice to the “lower” classes’. Yet this approach has often been based on the findings of a report by the National Council for Public Morals, with little investigation of the actual data supplied to the committee. Even accounts that have used some of this evidence position it as a minor component, exaggerated out of all proportion in order to satisfy the personal objectives of the moral purity campaigners.While there was a concerted effort throughout the Great War to highlight the perceived social ills of the cinema, I have attempted to present a more balanced account, which details the problems faced by cinemas during this period and the measures sought to improve them

Doppler cooling of gallium atoms: 2. Simulation in complex multilevel systems

This paper derives a general procedure for the numerical solution of the Lindblad equations that govern the coherences arising from multicoloured light interacting with a multilevel system. A systematic approach to finding the conservative and dissipative terms is derived and applied to the laser cooling of gallium. An improved numerical method is developed to solve the time-dependent master equation and results are presented for transient cooling processes. The method is significantly more robust, efficient and accurate than the standard method and can be applied to a broad range of atomic and molecular systems. Radiation pressure forces and the formation of dynamic dark-states are studied in the gallium isotope 66Ga.Comment: 15 pages, 8 figure
