Wei Fan v South Eastern Sydney Local Health District (No 2)

Wei Fan v South Eastern Sydney Local Health District (No 2)1 is a professional negligence decision given by Harrison AsJ on 31 August 2015. In this case, the plaintiff claimed damages for medical negligence on the basis of delayed diagnoses which caused him significant injuries. This case serves as a good example of the importance of credible lay and expert evidence, particularly where the facts include multiple hospitals and multiple admissions. This case also provides a reasonable example of the interplay between different mitigating defences including contributory negligence, failure to mitigate and volenti non fit injuria (voluntary assumption of risk). Ultimately, as the plaintiff’s evidence was not substantial or credible, the plaintiff’s claim failed. The court also went further and determined that (had the plaintiff been successful) there would have been a non-specific discount for contributory negligence

Test of ID carbon-carbon composite prototype tiles for the SPIDER diagnostic calorimeter

Additional heating will be provided to the thermonuclear fusion experiment ITER by injection of neutral beams from accelerated negative ions. In the SPIDER test facility, under construction at Consorzio RFX in Padova (Italy), the production of negative ions will be studied and optimised. To this purpose the STRIKE (Short-Time Retractable Instrumented Kalorimeter Experiment) diagnostic will be used to characterise the SPIDER beam during short operation (several seconds) and to verify if the beam meets the ITER requirement regarding the maximum allowed beam non-uniformity (below \ub110%). The most important measurements performed by STRIKE are beam uniformity, beamlet divergence and stripping losses. The major components of STRIKE are 16 1D-CFC (Carbon matrix-Carbon Fibre reinforced Composite) tiles, observed at the rear side by a thermal camera. The requirements of the 1D CFC material include a large thermal conductivity along the tile thickness (at least 10 times larger than in the other directions); low specific heat and density; uniform parameters over the tile surface; capability to withstand localised heat loads resulting in steep temperature gradients. So 1D CFC is a very anisotropic and delicate material, not commercially available, and prototypes are being specifically realised. This contribution gives an overview of the tests performed on the CFC prototype tiles, aimed at verifying their thermal behaviour. The spatial uniformity of the parameters and the ratio between the thermal conductivities are assessed by means of a power laser at Consorzio RFX. Dedicated linear and non-linear simulations are carried out to interpret the experiments and to estimate the thermal conductivities; these simulations are described and a comparison of the experimental data with the simulation results is presented

Isoscalar off-shell effects in threshold pion production from pd collisions

We test the presence of pion-nucleon isoscalar off-shell effects in the $pd\to \pi^+ t$ reaction around the threshold region. We find that these effects significantly modify the production cross section and that they may provide the missing strength needed to reproduce the data at threshold.Comment: 6 pages, REVTeX, twocolumn, including 3 figures (Postscript), uses psfig, updated and extended versio

Papel moderador del sexo en las prácticas de crianza

El objetivo del estudio fue analizar posibles diferencias en diversas conductas de crianza manifestadas por los padres y las madres en la socialización de hijos e hijas durante la adolescencia tardía y la adultez joven. Los participantes fueron 193 estudiantes de la Universidad de Granada, de los que 149 eran mujeres y 44 varones. Cumplimentaron el Cuestionario de Prácticas de Crianza (Supple et al., 2004), que evalúa seis dimensiones de la crianza, tanto del padre como de la madre: Apoyo, Inducción, Monitorización, Garantizar la Autonomía, Punitividad y Retirada del Afecto. Los resultados indican que hijos e hijas percibían una crianza diferencial por parte del padre, aunque sólo en dos de las dimensiones evaluadas (Inducción, Punitividad). Sin embargo, no percibían de modo diferente la crianza materna (únicamente se aproximaba a la significación la Retirada del afecto). En cuanto a las posibles diferencias en conductas de crianza por ambos progenitores, las madres prestaban unos mayores niveles de Apoyo, Inducción y Monitorización tanto con los hijos como con las hijas. La única dimensión de las conductas de crianza en la que las puntuaciones del padre superaban a las de la madre era en la Estimulación de la Autonomía con los hijos varones, aunque sin llegar al nivel de significación estadística. Finalmente, en lo que se refiere al uso de métodos de disciplina inadecuados, las madres mostraban una mayor Punitividad que los padres con las hijas, mientras que en el caso de los hijos las madres también puntuaban significativamente más que los padres en Retirada del Afecto.Universidad de Málaga.

Antecedentes de las prácticas de crianza: el papel de los conflictos entre los padres

El objetivo de la investigación fue analizar el impacto que puede tener la conflictividad de los padres en las prácticas de crianza que utilizan con los hijos. Además, esa posible relación se estudia con padres y madres, y en función del sexo de los hijos. Los participantes fueron 191 estudiantes universitarios, 44 varones y 147 mujeres, que contestaron un cuestionario sobre conflictos entre los padres (OPS de Porter y O’Leary, 1988) y el cuestionario de prácticas de crianza de Supple et al. (2004). Los resultados confirmaron la relación significativa existente entre conflictividad de pareja y las conductas de crianza mantenidas con los hijos. La puntuación total en conflictividad se relacionaba significativamente con las seis dimensiones de crianza utilizadas con las hijas por padres y madres. En el caso de los hijos, sin embargo, los conflictos se relacionaban con todas las dimensiones de crianza del padre, y solamente con dos de la madre. Los conflictos específicos por la crianza repercutían por igual en los niveles de apoyo y autonomía mantenidos por padres y madres con las hijas, así como en el uso de prácticas de crianza negativas. Sin embargo, en el caso de los hijos, la conflictividad predecía las prácticas negativas de ambos progenitores, pero sólo se resentían las dimensiones de crianza positiva del padre. Finalmente, la conflictividad más intensa (puntuación en agresiones verbales) se asociaba fuertemente con un menor uso por padres y madres de prácticas de crianza positivas con las hijas y una mayor utilización por ambos de métodos negativos, mientras que en el caso de los hijos sólo se asociaba con el uso de métodos de crianza negativos por parte del padre.Universidad de Málaga.

The one-pion-exchange three-nucleon force and the AyA_y puzzle

We consider a new three-nucleon force generated by the exchange of one pion in the presence of a 2N correlation. The underlying irreducible diagram has been recently suggested by the authors as a possible candidate to explain the puzzle of the vector analyzing powers $A_y$ and $iT_{11}$ for nucleon-deuteron scattering. Herein, we have calculated the elastic neutron-deuteron differential cross section, $A_y$, $iT_{11}$, $T_{20}$, $T_{21}$, and $T_{22}$ below break-up threshold by accurately solving the Alt-Grassberger-Sandhas equations with realistic interactions. We have also studied how $A_y$ evolves below 30 MeV. The results indicate that this new 3NF diagram provides one possible additional contribution, with the correct spin-isospin structure, for the explanation of the origin of this puzzle.Comment: revised version: We have also studied how Ay evolves below 30 MeV, 4 Pages (twocolumn), 2 figures, uses psfig, RevTe

Designing high efficiency glow discharge cleaning systems

In this paper we present our studies about the choices of anode design and operational regime in order to get high efficiency glow discharge cleaning of the first wall of a fusion device. We analyzed a database of toroidal and poloidal profiles of the ion current density at the wall, measured by electrostatic probes embedded in RFX-mod first wall tiles, taken in different configurations. The ion current at the wall, both global and local, is in fact strictly connected to the cleaning efficiency, since during glow discharge the wall is physically sputtered by the ions. We found that small size anodes and high in-vessel pressure lead to the peaking of the current profile around the anodes locations, and we experimentally characterized this effect. Instead, we found that anode radial position in the poloidal section has negligible effect on current density profile, even when the anodes are placed at the first wall. Finally, the most convenient operational regime, in terms of pressure and current, has been proposed. Keywords: RFX-mod, Glow discharge, Wall cleaning, Ion current profile, Anode desig

Why is the three-nucleon force so odd?

By considering a class of diagrams which has been overlooked also in the most recent literature on three-body forces, we extract a new contribution to the three-nucleon interaction which specifically acts on the triplet odd states of the two nucleon subsystem. In the static approximation, this 3N-force contribution is fixed by the underlying 2N interaction, so in principle there are no free parameters to adjust. The 2N amplitude however enters in the 3NF diagram in a form which cannot be directly accessed or constrained by NN phase-shift analysis. We conclude that this new 3N-force contribution provides a mechanism which implies that the presence of the third nucleon modifies the p-wave (and possibly the f-wave) components of the 2N subsystem in the triplet-isotriplet channels.Comment: 10 Pages, 7 figures, RevTeX, twocolumn, epsf (updated version with minor changes
