Precipitation of acute psychotic episodes by intensive meditation in individuals with a history of schizophrenia
Solving the kilo-second QPO problem of the intermediate polar GK Persei
We detect the likely optical counterpart to previously reported X-ray QPOs in
spectrophotometry of the intermediate polar GK Persei during the 1996 dwarf
nova outburst. The characteristic timescales range between 4000--6000 s.
Although the QPOs are an order of magnitude longer than those detected in the
other dwarf novae we show that a new QPO model is not required to explain the
long timescale observed. We demonstrate that the observations are consistent
with oscillations being the result of normal-timescale QPOs beating with the
spin period of the white dwarf. We determine the spectral class of the
companion to be consistent with its quiescent classification and find no
significant evidence for irradiation over its inner face. We detect the white
dwarf spin period in line fluxes, V/R ratios and Doppler-broadened emission
profiles.Comment: 14 pages, 11 figures. Accepted for publication in MNRA
Quantum turbulence at finite temperature: the two-fluids cascade
To model isotropic homogeneous quantum turbulence in superfluid helium, we
have performed Direct Numerical Simulations (DNS) of two fluids (the normal
fluid and the superfluid) coupled by mutual friction. We have found evidence of
strong locking of superfluid and normal fluid along the turbulent cascade, from
the large scale structures where only one fluid is forced down to the vorticity
structures at small scales. We have determined the residual slip velocity
between the two fluids, and, for each fluid, the relative balance of inertial,
viscous and friction forces along the scales. Our calculations show that the
classical relation between energy injection and dissipation scale is not valid
in quantum turbulence, but we have been able to derive a temperature--dependent
superfluid analogous relation. Finally, we discuss our DNS results in terms of
the current understanding of quantum turbulence, including the value of the
effective kinematic viscosity
Vortex spectrum in superfluid turbulence: interpretation of a recent experiment
We discuss a recent experiment in which the spectrum of the vortex line
density fluctuations has been measured in superfluid turbulence. The observed
frequency dependence of the spectrum, , disagrees with classical
vorticity spectra if, following the literature, the vortex line density is
interpreted as a measure of the vorticity or enstrophy. We argue that the
disagrement is solved if the vortex line density field is decomposed into a
polarised field (which carries most of the energy) and an isotropic field
(which is responsible for the spectrum).Comment: Submitted for publication

Promoting positive communication environments: a service evaluation.
Purpose
The purpose of this paper is to present an evaluation of a programme of training and support provided to staff, which aimed to encourage supported communication environments for people with learning disabilities.
Design/methodology/approach
Training, monitoring and support for communication, specifically augmentative and alternative communication (AAC) strategies, was provided by speech and language therapy staff to two residential services over 46 weeks. Staff and service user communications were observed pre- and post-intervention.
Findings
In one provision there was an increase in service user initiations and the use of some AAC strategies by support staff. In the other provision there was no change in service user initiations and a decrease in the range of AAC strategies used. It appears that some forms for AAC remain challenging for staff to implement.
Originality/value
This evaluation explores ways of using specialist support services to improve communication environments for people with learning difficulties. Possible reasons for differences in the outcome of the intervention are discussed. Future research into the types of communication interactions experienced by people with learning disabilities across the range of communication styles may be useful so that support staff can be better helped to provide sustained and enriched communication environments
Identification and Characterisation of Technological Topics in the Field of Molecular Biology
This paper focuses on methodological approaches for characterising the
specific topics within a technological field based on scientific literature
data. We introduce a diachronic clustering analysis approach and some
bibliometric indicators. The results are visualised with the software-tool
Stanalyst [1]. We are applying our methods to the field "Molecular Biology".

The relationship between faith maturity and life satisfaction
Background
Studies have been conducted that conclude that having a more mature faith correlates to healthier psychological well-being and healthier personal relationships (Hill & Pargament, 2003; Okun & Stock, 1987; Powell & Pepper, 2015). A significant amount of research has been conducted on life satisfaction, however fewer studies have explored the relationship between life satisfaction and faith maturity. Hawkins, Tan, and Turk (1999) compared a secular inpatient cognitive-behavioral therapy program to a Christian inpatient cognitive-behavioral therapy program and discovered that there was a negative correlation between spiritual well-being and depression, but little has been done beyond this study to examine this relationship. Alessandri, Caprara, and Tisak (2012) also showed that there is a relationship between life orientation and life satisfaction, as well as self-esteem and life satisfaction.
Methods and Procedures
A survey was sent to the entire student body of 2,900 students at a Christian liberal arts university in the Midwest and 717 responses were received. The survey included questions from Benson, Donahue, and Ericksonâs Faith Maturity Scale (1993), Diener, Emmons, Larsen, and Griffinâs Satisfaction with Life Scale (1985), Scheier, Carver, and Bridgesâ Revised Life Orientation Test (1994), Rosenbergâs Self Esteem Scale (1965), and demographic questions.
Results
There was a statistically significant correlation between faith maturity and life satisfaction, although less variability in life satisfaction could be predicted from faith maturity than from self-esteem and life orientation. Using an independent samples t-test, it was found that the life satisfaction of participants in this study was greater than the participants in Diener, et al.âs (1985) study on life satisfaction.
Conclusion
A significant positive correlation was found between faith maturity and life satisfaction, although this correlation was slightly smaller than the other correlations that were assessed. It was also found that 18 percent of variability in life satisfaction could be predicted by faith maturity
