Violence is conceptualized as an attempt to achieve justice. The cycle of violence is explored with reference to the early experience of perpetrators and their treatment by the criminal justice system after they have committed acts of violence. Aetiology The origins of violence are considered in the context of the experience of trauma in childhood and the consequent damage to ,internal working models' of relationships. The perpetration of violence in later life is viewed in the context of identifying with the aggressor, the obliteration of thought processes and the repetition of the earlier childhood trauma. The offence is considered as a symptom, a symbolic communication, by individuals who are unable to symbolize distress on a verbal level. The institutional response The ,violence begets violence' hypothesis is then extended to include the response of society and its institutions as part of the full circle of the repetition compulsion: the childhood victim who later becomes a perpetrator, then again becomes the victim of a cruel and persecuting system. Incarceration is viewed as a ,compromise formation' in that it fulfils the wish both for punishment and for care, albeit in a highly disguised form and allowing for a defensive state of mind to continue. The therapeutic relationship These issues are considered in the context of the therapeutic relationship and the enactment of early trauma in this setting which may provide insight into the psychological processes at work between the offender and society. Conclusions Understanding violence indicates that, whilst some individuals need to be physically checked, a response which focuses on retribution fails to address the problem of violence and colludes with the very pathology of those who engage in such action.

Huang Abstract The hybrid particle method (HPM) is a particle-based method for the solution of high-speed dynamic structural problems. In the current formulation of the HPM, a moving least-squares (MLS) interpolant is used to compute the derivatives of stress and velocity components. Compared with the use of the MLS interpolant at interior particles, the boundary particles require two additional treatments in order to compute the derivatives accurately. These are the rotation of the local co-ordinate system and the imposition of boundary constraints, respectively. In this paper, it is first shown that the derivatives found by the MLS interpolant based on a complete polynomial are indifferent to the orientation of the co-ordinate system. Secondly, it is shown that imposing boundary constraints is equivalent to employing ghost particles with proper values assigned at these particles. The latter can further be viewed as placing the boundary particle in the centre of a neighbourhood that is formed jointly by the original neighbouring particles and the ghost particles. The benefit of providing a symmetric or a full circle of neighbouring points is revealed by examining the error terms generated in approximating the derivatives of a Taylor polynomial by using a linear-polynomial-based MLS interpolant. Symmetric boundaries have mostly been treated by using ghost particles in various versions of the available particle methods that are based on the strong form of the conservation equations. In light of the equivalence of the respective treatments of imposing boundary constraints and adding ghost particles, an alternative treatment for symmetry boundaries is proposed that involves imposing only the symmetry boundary constraints for the HPM. Numerical results are presented to demonstrate the validity of the proposed approach for symmetric boundaries in an axisymmetric impact problem. Copyright © 2005 John Wiley & Sons, Ltd. [source] Finite volume method with zonal-embedded grids for cylindrical coordinatesINTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN FLUIDS, Issue 3 2006Yong Kweon Suh Abstract A zonal-embedded-grid technique has been developed for computation of the two-dimensional Navier,Stokes equations with cylindrical coordinates. As is well known, the conventional regular grid system gives very small grid spacings in the azimuthal direction so it requires a very small time step for a stable numerical solution when the explicit method is used. The fundamental idea of the zonal-embedded-grid technique is that the number of azimuthal grids can be made small near the origin of the coordinates so that the grid size is more uniformly distributed over the domain than with the conventional regular-grid system. The code developed using this technique combined with the explicit, finite-volume method was then applied to calculation of the asymmetric swirl flows and Lamb's multi-polar vortex flows within a full circle and the spin-up flows within a semi-circle. It was shown that the zonal-embedded grids allow a time step far larger than the conventional regular grids. For the case of the Lamb's multi-polar vortex flows, the code was validated by comparing the calculated results with the exact solutions. For the case of the semi-circle spin-up flows, the experimental results were used for the verification. It was seen that the numerical results were in good agreement with the experimental results both qualitatively and quantitatively. Copyright © 2006 John Wiley & Sons, Ltd. [source] Geographies of the financial crisisAREA, Issue 1 2009Manuel Aalbers Real estate is, by definition, local as it is spatially fixed. Mortgage lending, however, has developed from a local to a national market and is increasingly a global market today. An understanding of the financial crisis is ultimately a spatialised understanding of the linkages between local and global. This article looks at the geographies of the mortgage crisis and credit crunch and asks the question: how are different places affected by the crisis? The article looks at different states, different cities, different neighbourhoods and different financial centres. Investors in many places had invested in residential mortgage backed securities and have seen their value drop. Housing bubbles, faltering economies and regulation together have shaped the geography of the financial crisis on the state and city level in the US. Subprime and predatory lending have affected low-income and minority communities more than others and we therefore not only see a concentration of foreclosures in certain cities, but also in certain neighbourhoods. On an international level, the long-term economical and political consequences of this are still mostly unknown, but it is clear that some financial centres in Asia (including the Middle East) will become more important now that globalisation is coming full circle. This article does not present new empirical research, but brings together work from different literatures that all in some way have a specific angle on the financial crisis. The aim of this article is to make the geographical dimensions of the financial crisis understandable to geographers that are not specialists in all , or even any , of these literatures, so that they can comprehend the spatialisation of this crisis. [source] Outcome of pregnancies achieved by in vitro fertilisation techniques and diagnosed as twins at the 6 week ultrasoundAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 6 2004Gabor T. KOVACS Abstract Background: To bring the success rate of in vitro fertilisation (IVF) procedures to an acceptable level, multiple embryos have historically been replaced. This has resulted in an ,epidemic' of multiple births. The pendulum has now swung full circle and the number of embryos transferred is now being limited. Such high numbers of IVF twins will not be produced in the future. Aim: To review retrospectively the outcome of a series of pregnancies achieved by IVF where the 6 week ultrasound showed the presence of two sacs. Methods: Retrospective study in a university IVF programme that produced 746 IVF pregnancies with twins at 6 weeks of gestation (1991,1999). Results: The main outcome measures were perinatal mortality, pregnancy outcome, gestation at delivery and obstetrics complications reported. Interestingly, by 20 weeks gestation, 184 (24.7%) of pregnancies spontaneously reduced to a singleton, whereas 49 (6.6%) lost both twins. Of the 513 (68.8%) viable twin pregnancies (>20 weeks), 154 (20.6%) went on to term (>37 weeks), whereas 250 (33.5%) delivered between 33 and 36 weeks gestation. The perinatal mortality per 1000 births was 6.5 over 37 weeks, 8.0 for 33,36 weeks, 41.7 for 29,32 weeks and 500 for under 28 weeks. [source] Research an exciting journey and a career statement: a means to an end, putting rurality on the nursing research agendaAUSTRALIAN JOURNAL OF RURAL HEALTH, Issue 6 2004Sonia Allen Abstract Two issues were of importance to nurses in rural areas considering postgraduate studies. The first was the need for part-time study and what this entails. The second was a request that there be no research component within the postgraduate courses they identified. It is this second issue that I wish to address. I was a nonbeliever in the merit of research studies being integrated into nursing specialist programs. Following a long career in rural clinical nursing and management I have come full circle and now acknowledge the need to understand the role to base practice evidence that is generated through empirical research.
