With a little help from FUN FRIENDS young children can overcome anxiety
This paper highlights resilience as a key concept when working with young children to improve their emotional wellbeing and reduce anxieties. Supporting children aged 4-7 years with anxiety is a significant area of advancement in terms of therapeutic approaches over the last decade. This paper outlines one such approach that was implemented within a Tier 2 Community Child and Adolescent Mental Health Service (CAMHS) within the northern region of England to determine whether findings from Australian studies could be replicated in the UK. A pilot study was undertaken with a group of young children aged 4-7 years old with symptoms of anxiety. All of the children had been referred to the service because of anxiety related issues, such as social phobia, generalised anxiety disorder and obsessive-compulsive disorder. They received a group intervention, FUN FRIENDS, over a period of 12 weeks. By enabling the children to become more self-sufficient this allowed greater emotional and social skills development. All the children demonstrated improved anxiety scores post intervention, as measured by the Spence Child Anxiety Scale
The Non-Linear Growth of the Magnetic Rayleigh-Taylor Instability
This work examines the effect of the embedded magnetic field strength on the
non-linear development of the magnetic Rayleigh-Taylor Instability (RTI) (with
a field-aligned interface) in an ideal gas close to the incompressible limit in
three dimensions. Numerical experiments are conducted in a domain sufficiently
large so as to allow the predicted critical modes to develop in a physically
realistic manner. The ratio between gravity, which drives the instability in
this case (as well as in several of the corresponding observations), and
magnetic field strength is taken up to a ratio which accurately reflects that
of observed astrophysical plasma, in order to allow comparison between the
results of the simulations and the observational data which served as
inspiration for this work. This study finds reduced non-linear growth of the
rising bubbles of the RTI for stronger magnetic fields, and that this is
directly due to the change in magnetic field strength, rather than the indirect
effect of altering characteristic length scales with respect to domain size. By
examining the growth of the falling spikes, the growth rate appears to be
enhanced for the strongest magnetic field strengths, suggesting that rather
than affecting the development of the system as a whole, increased magnetic
field strengths in fact introduce an asymmetry to the system. Further
investigation of this effect also revealed that the greater this asymmetry, the
less efficiently the gravitational energy is released. By better understanding
the under-studied regime of such a major phenomenon in astrophysics, deeper
explanations for observations may be sought, and this work illustrates that the
strength of magnetic fields in astrophysical plasmas influences observed RTI in
subtle and complex ways.Comment: Accepted for publication by A&A. 10 pages, 9 figure

Mating Success of Gypsy Moth (Lepidoptera: Lymantriidae) Females in Southern Wisconsin
Mating success of laboratory-reared gypsy moth Lymantria dispar (L.) females exposed for 24 hr on tree boles and its relationship to male moth counts in pheromone-baited traps was studied in southern Wisconsin. The relationship between mating probability of gypsy moth females and male moth counts in traps corresponded to an exponential model that can be used for predicting mating probabilities in sparse isolated populations. Relative attractiveness of females compared with traps was 0.23, which is similar to earlier estimated relative attractiveness of females in Virginia. The mortality of females from predation, however, was found to be significantly lower in Wisconsin than in Virginia, which may contribute to a larger degree of mating success. Increased long-distance dispersal of males could also contribute to the increased mating success of females. The higher rate of spread of gypsy moth populations in Wisconsin compared with other areas may be due to the increased mating success caused by the lower female mortality and higher long-distance dispersal of males
