On Static and Dynamic Heterogeneities in Water
We analyze differences in dynamics and in properties of the sampled potential
energy landscape between different equilibrium trajectories, for a system of
rigid water molecules interacting with a two body potential. On entering in the
supercooled region, differences between different realizations enhance and
survive even when particles have diffused several time their average distance.
We observe a strong correlation between the mean square displacement of the
individual trajectories and the average energy of the sampled landscape
What happens when interviewers ask repeated questions in forensic interviews with children alleging abuse?
This study was designed to explore 1) the ways in which interviewers refocus alleged victims of abuse on their previous responses and 2) how children responded when they were refocused on their previous responses. Transcripts of 37 forensic interviews conducted by British police officers trained using the best practices spelled out in the Memorandum of Good Practice were examined. The instances in which interviewers asked repeated questions were isolated and coded into categories with respect to the reasons why interviewers needed to ask the repeated question (i.e., there was no apparent reason, to challenge a child’s response, clarification, no answer the first time the question was asked, digression, or compound question). The children’s responses to the repeated questions were further categorised into mutually exclusive categories (i.e., elaboration, repetition, contradiction, or no answer). On average interviewers asked children 8 repeated questions per interview. Most of the time interviewers asked repeated questions to challenge a previous response (62%), but they were also sometimes asked for no apparent reason (20%). Children repeated previous responses or elaborated on a previous response 81% of the time and contradicted themselves 7% of the time when re-asked the same question. We conclude that children did not appear unduly pressured to change their answers, and, more importantly, did not contradict themselves when interviewers attempted to refocus them on particular responses
Magnetic Response in Anyon Fluid at High Temperature
The magnetic response of the charged anyon fluid at temperatures lower and
larger than the fermion enery gap is investigated in the
self-consistent field approximation. We prove that the anyon system with
boundaries exhibits a total Meissner effect at temperatures smaller than the
fermion energy gap (). The London penetration length at
is of the order . At a
new phase, characterized by an inhomogeneous magnetic penetration, is found. We
conclude that the energy gap, defines a scale that separates two
phases: a superconducting phase at , and a non-superconducting
one at .Comment: 7 pages, Talk presented at SILAFAE'98. April 8-11, 1998, San Juan,
