We investigate the persistence of spectral gaps of one-dimensional frustration free quantum lattice systems under weak perturbations and with open boundary conditions. Assuming that the interactions of the system satisfy a form of local topological quantum order, we prove explicit lower bounds on the ground state spectral gap and higher gaps for spin and fermion chains. By adapting previous methods using the spectral flow, we analyze the bulk and edge dependence of lower bounds on spectral gaps
Cyberporn and moral panic: an evaluation of press reactions to pornography on the internet.
A summary of the MA Dissertation which won the 2002 Library and Information Research Group Student Prize. The aim of the Dissertation was to find out if there had been a moral panic in the British press over Internet content. The paper briefly looks at the background to the Study. The term “moral panic” is defined in terms of Stanley Cohen’s (1972) model and put into context. The Literature Review looks at whether there has been a moral panic over Internet content in the USA, and at the situation in Britain. The legal and regulatory context is explored. The methodology of the Study is then discussed, considering which media were chosen and why, the timescale of the Study and how the data was collected and analysed. The limitations of the methodology are reviewed. The results are then presented, with an explanation of how they coincide with Cohen’s model. The Study concludes that there has been a moral panic over Internet content, which began in the latter half of 1995. Options for future study into this area are then offered
