Long-range automaton models of earthquakes: Power-law accelerations, correlation evolution, and mode-switching

We introduce a conceptual model for the in-plane physics of an earthquake fault. The model employs cellular automaton techniques to simulate tectonic loading, earthquake rupture, and strain redistribution. The impact of a hypothetical crustal elastodynamic Green's function is approximated by a long-range strain redistribution law with a r(-p) dependance. We investigate the influence of the effective elastodynamic interaction range upon the dynamical behaviour of the model by conducting experiments with different values of the exponent (p). The results indicate that this model has two distinct, stable modes of behaviour. The first mode produces a characteristic earthquake distribution with moderate to large events preceeded by an interval of time in which the rate of energy release accelerates. A correlation function analysis reveals that accelerating sequences are associated with a systematic, global evolution of strain energy correlations within the system. The second stable mode produces Gutenberg-Richter statistics, with near-linear energy release and no significant global correlation evolution. A model with effectively short-range interactions preferentially displays Gutenberg-Richter behaviour. However, models with long-range interactions appear to switch between the characteristic and GR modes. As the range of elastodynamic interactions is increased, characteristic behaviour begins to dominate GR behaviour. These models demonstrate that evolution of strain energy correlations may occur within systems with a fixed elastodynamic interaction range. Supposing that similar mode-switching dynamical behaviour occurs within earthquake faults then intermediate-term forecasting of large earthquakes may be feasible for some earthquakes but not for others, in alignment with certain empirical seismological observations. Further numerical investigation of dynamical models of this type may lead to advances in earthquake forecasting research and theoretical seismology.

Cross-border insolvency: Adoption of CLERP 8 as an evolution of Australian insolvency law

In 1997 the United Nations adopted the UNCITRAL Model Law on Cross-Border Insolvency and recommended that member states adopt it as part of domestic legislation. In 2002 Australia, an active participant in UNCITRAL's Working Group on Insolvency Law, announced that the next phase of the Commonwealth Government's Corporate Law Economic Reform Program would be a review of cross-border insolvency law. CLERP 8 seeks feedback on the proposed enactment of the Model Law by a separate Commonwealth statute. This article places such a development within the context of Australian cross-border insolvency law as it has evolved from early English bankruptcy legislation through case law arising from the banking collapses of the late 19th century to the more recent jurisprudence produced by corporate collapses of the late 1980s to early 1990s and current high-profile insolvencies.

Reforming the law of medical negligence: Solutions in search of a problem

The Commonwealth Government's Principles Based Review of the Law of Negligence recently recommended reforms aimed at limiting liability and damages arising from personal injury and death, in response to the growing perception that the current system of compensating personal injury had become financially unsustainable. Recent increases in medical liability and damages have eroded the confidence of doctors and their professional bodies, with fears of unprecedented desertion from and reduced recruitment into high risk areas, and one of the primary foci of the review concerned medical negligence. The article analyses proposals to redefine the principles necessary for the finding of negligence, against the terms of reference of the review. The article assumes that for the foreseeable future, Australia will persist with tort-based compensation for personal injury rather than developing a no-fault scheme. If the suggested changes to the fundamental principles of negligence are unlikely to reduce medical liability, greater attention might be given to the processes which come into play after the finding of negligence, where reform is more likely to benefit both plaintiffs and defendants.

Discovering the Law Again: John Grisham, Ed Stevens and the Postmaterial Lawyer

This paper uses three films adapted from the novels of John Grisham, The Firm, The Rainmaker and A Time To Kill, as well as associated television series like Ed to map a vernacular theory of what I have termed the 'postmaterial' lawyer. Grisham's work has been the focus of much critique by legal scholars who suggests he hates lawyers, is critical of the concept of law, and provides 'outlandishly' happy endings. I will challenge these critiques and, in tracing the history of legal thrillers and trial movies, suggest that Grisham and the related texts' explorations of how a just practitioner can operate in an unjust system constitute a powerful interrogation of what law can be.

Agenda social registro civil de nascimento e documenta????o b??sica: comit??s gestores da agenda social

Esta ?? uma iniciativa de gest??o para implementa????o da Agenda Social Registro Civil de Nascimento e Documenta????o B??sica, envolvendo uma rede de ??rg??os e institui????es de diversos poderes da Rep??blica nos tr??s n??veis administrativos do estado brasileiro, bem como institui????es da sociedade civil e organismos internacionais, a partir da atua????o de comit??s gestores em n??vel central e descentralizados. A agenda possibilitou intervir na forma????o de uma cultura de inclus??o a partir da documenta????o civil, com base na realiza????o das campanhas em n??vel nacional. Um dos resultados da implementa????o da agenda ?? a queda do ??ndice de sub-registro de nascidos vivos, que era de 20,9% em 2002, e passou para 12,2% em 2007

Relat??rio final do projeto desenvolvimento de capacidade de lideran??a (Brasil-Canad??)

Desde o in??cio de 2000, a Canada School of Public Service (CSPS) e a Escola Nacional de Administra????o P??blica (ENAP) demonstraram interesse na possibilidade de coopera????o para desenvolver capacidades de gest??o de servidores p??blicos brasileiros. Um acordo assinado em 2003, inicialmente foi planejado para ser uma parceria de tr??s anos entre as duas escolas. No entanto, a parceria continua at?? hoje e agora estamos no final do segundo, e ??ltimo projeto de coopera????o t??cnica financiado pela Canadian International Development Agency (CIDA) entre Brasil e Canad??, denominado ???Desenvolvimento da Capacidade de Governan??a???. Este relat??rio representa o resultado deste segundo projeto, o qual ampliou o esfor??o de capacita????o da primeira parceria, focando agora em funcion??rios p??blicos mais pr??ximos da "linha de frente" da presta????o de servi??os, aumentando assim a efic??cia do governo nessas ??reas. O projeto mostrou ser bem-sucedido, principalmente, porque seguiu de perto os princ??pios do desenvolvimento eficaz e sustent??vel. Considerando a sua miss??o de desenvolver compet??ncias de servidores p??blicos, a ENAP deu prioridade, dentro deste projeto de coopera????o com o Canad??, a atividades que visam refor??ar a capacidade de governan??a do pa??s, trabalhando em conjunto com escolas em cinco regi??es: Norte, Nordeste, Centro-Oeste, Sudeste e Sul, com especial ??nfase nas ??reas mais pobres do pa??s, localizadas nas regi??es Norte e Nordeste. Foram participantes-chave neste projeto: i) seis escolas brasileiras regionais de administra????o p??blica; ii) uma das principais institui????es acad??micas do Canad?? - Queen's University, e iii) o Minist??rio do Desenvolvimento Social e Combate ?? Fome e tr??s Secretarias de Ra??a, Direitos Humanos e Pol??ticas para as Mulheres. Neste projeto, a CSPS compartilhou suas metodologias em educa????o a dist??ncia, lideran??a e gest??o p??blica. Trabalhando com parceiros brasileiros, ela tamb??m transferiu e adaptou curr??culos e conte??dos de seus cursos. A CIDA forneceu $1.845.000,00 por meio da Programa de Interc??mbio de Conhecimentos para a Promo????o da Eq??idade (PIPE) Brasil-Canad??. A ENAP e as EPBs contribu??ram com $993,752 e a CSPS contribuiu com material de curso, conhecimento e apoio t??cnico no valor de $ 1.000.000
