One-year follow-up of family versus child CBT for anxiety disorders: Exploring the roles of child age and parental intrusiveness.
ObjectiveTo compare the relative long-term benefit of family-focused cognitive behavioral therapy (FCBT) and child-focused cognitive behavioral therapy (CCBT) for child anxiety disorders at a 1-year follow-up.MethodThirty-five children (6-13 years old) randomly assigned to 12-16 sessions of family-focused CBT (FCBT) or child-focused CBT (CCBT) participated in a 1-year follow-up assessment. Independent evaluators, parents, and children rated anxiety and parental intrusiveness. All were blind to treatment condition and study hypotheses.ResultsChildren assigned to FCBT had lower anxiety scores than children assigned to CCBT on follow-up diagnostician- and parent-report scores, but not child-report scores. Exploratory analyses suggested the advantage of FCBT over CCBT may have been evident more for early adolescents than for younger children and that reductions in parental intrusiveness may have mediated the treatment effect.ConclusionFCBT may yield a stronger treatment effect than CCBT that lasts for at least 1 year, although the lack of consistency across informants necessitates a circumspect view of the findings. The potential moderating and mediating effects considered in this study offer interesting avenues for further study
Creation of two-dimensional coulomb crystals of ions in oblate Paul traps for quantum simulations
We develop the theory to describe the equilibrium ion positions and phonon
modes for a trapped ion quantum simulator in an oblate Paul trap that creates
two-dimensional Coulomb crystals in a triangular lattice. By coupling the
internal states of the ions to laser beams propagating along the symmetry axis,
we study the effective Ising spin-spin interactions that are mediated via the
axial phonons and are less sensitive to ion micromotion. We find that the axial
mode frequencies permit the programming of Ising interactions with inverse
power law spin-spin couplings that can be tuned from uniform to with
DC voltages. Such a trap could allow for interesting new geometrical
configurations for quantum simulations on moderately sized systems including
frustrated magnetism on triangular lattices or Aharonov-Bohm effects on ion
tunneling. The trap also incorporates periodic boundary conditions around loops
which could be employed to examine time crystals.Comment: 17 pages, 8 figures, submitted to the journal EPJ Quantum Technology

Helminth Parasites of Rails and Host-Parasite Relationships of the Trematode Protechinostoma mucronisertulatum
In a survey of 15 soras (Porzana carolina) and 31 Virginia rails (Rallus limicola) collected in Iowa during May-September 1963, Protechinostoma mucronisertulatum was the most frequently encountered trematode of the sora. It does not occur in the Virginia rail. Experimentally-developed metacercariae and adults were obtained and host-parasite relationships studied with special reference to annual incidence of infection in snails. Additional helminths of the sora and the Virginia rail include several representing new host records
Deep Halpha imagery of the Eridanus shells
A deep \ha image of interlocking filamentary arcs of nebulosity has been
obtained with a wide-field ( 30\degree diameter) narrow-band filter
camera combined with a CCD as a detector. The resultant mosaic of images,
extending to a galactic latitude of 65, has been corrected for field
distortions and had galactic coordinates superimposed on it to permit accurate
correlations with the most recent H{\sc i} (21 cm), X-ray (0.75 kev) and FIR
(IRAS 100 m) maps.
Furthermore, an upper limit of 0.13 arcsec/yr to the expansion proper motion
of the primary 25\degree long nebulous arc has been obtained by comparing a
recent \ha image obtained with the San Pedro Martir telescope of its
filamentary edge with that on a POSS E plate obtained in 1951.
It is concluded that these filamentary arcs are the superimposed images of
separate shells (driven by supernova explosions and/or stellar winds) rather
than the edges of a single `superbubble' stretching from Barnard's Arc (and the
Orion Nebula) to these high galactic latitudes. The proper motion measurement
argues against the primary \ha emitting arc being associated with the giant
radio loop (Loop 2) except in extraordinary circumstances.Comment: 9 pages, 5 figures, accepted for MNRAS publicatio
Engineering - young people want to be informed
Young people in developed nations recognise the contribution that science and technology make to society and acknowledge their importance now and in the future, yet few view their study as leading to interesting careers. Some countries are taking action to raise interest in science, technologies, engineering and mathematics and increase the number of students studying these subjects. One of the barriers to young people pursuing engineering is their limited or distorted perception of it - they associate it only with building and fixing things. Young people rarely encounter engineers, unlike other professionals, engineering has little or no advocacy in the media and there are few opportunities to experience engineering. Many of the pupils surveyed at the start of Engineering the Future, a three year EPSRC-funded project, wrote âdonât know what engineering isâ and/or âwould like more informationâ. This paper reports on work with researchers, policy makers and practitioners in Scotland to develop a sustainable model of activities and interactions that develops pupilsâ understanding of the nature of engineering, embeds experiences of engineering within the school classroom and curriculum and promotes engineering as a career. After learning about engineering through the activities the pupilsâ perceptions had improved. Almost all considered it important that young people know about engineering, because it is an essential part of everyday life and, in the words of one pupil - âIf we know more about it, our minds wouldnât stay closed to it. We would maybe take it up.
Response to comment on "solid recovered fuel: Materials flow analysis and fuel property development during the mechanical processing of biodried waste"
Laner and Cencic1 comment on Velis et al. (2013)2 clarifying certain points on the use of the material flow analysis (MFA) software STAN3. We welcome the correspondence and the opportunity this exchange provides to discuss optimal approaches to using STAN. In keeping with Velis et al.2 these physically impossible, and otherwise insignificant, negative flows have enabled improvements to STAN. Here, we elaborate on the practicalities of using STAN in our research and on the correctness and validation of our results, notwithstanding the inclusion of negative flows. We explain the contribution of our approach to solid waste management and resource recovery
Standards for CHERG reviews of intervention effects on child survival
Background The Lives Saved Tool (LiST) uses estimates of the effects of interventions on cause-specific child mortality as a basis for generating projections of child lives that could be saved by increasing coverage of effective interventions. Estimates of intervention effects are an essential element of LiST, and need to reflect the best available scientific evidence. This article describes the guidelines developed by the Child Health Epidemiology Reference Group (CHERG) that are applied by scientists conducting reviews of intervention effects for use in LiST
