TAKE ME BACK TO MOVE ME FORWARD: RE-ENACTMENT OF THE FAMILY SYSTEM AS A PATHWAY TO BETTER QUALITY OF LIFE FOR ALEXITHYMIC PATIENTS IN GROUP THERAPY

Background: Despite much attention in the clinical literature, research on alexithymia in the treatment setting has only recently gained traction. While several reports indicate limited benefit from therapy amongst patients with high alexithymia, this seems to be less so in the context of group therapy. This study considers a specific aspect of the group therapy process - family re-enactment - in facilitating improvement in overall quality of life for patients with high levels of alexithymia. Subjects and methods: Family re-enactment was examined as a potential mediator of the relationship between alexithymia and change in quality of life among 50 patients who completed treatment in an intensive, integrative group therapy programme. Patients completed three self-report measures: Toronto Alexithymia Scale-20 (baseline), Quality of Life Inventory (baseline, post-therapy), and Therapeutic Factors Inventory-Short Form (week 8). Regression with mediation analysis was employed using the change score for the QOLI as the dependent variable, alexithymia scores as the independent variable, and the family re-enactment score as the mediator; baseline quality of life was included in the model as a control variable. Results: Family re-enactment emerged as a significant mediator of the relationship between alexithymia and treatment outcome, implicating it as a contributing mechanism of change for alexithymic patients who participate in group therapy. Conclusion: Patients with higher levels of alexithymia (in particular, difficulty identifying and describing feelings) were more likely to positively endorse aspects of family re-enactment during group therapy, which in turn were significantly associated with greater improvement in patients’ overall quality of life

XMM-Newton Surveys of the Canada-France Redshift Survey Fields - III: The Environments of X-ray Selected AGN at 0.4<z<0.6

The environmental properties of a sample of 31 hard X-ray selected AGN are investigated, from scales of 500 kpc down to 30 kpc, and are compared to a control sample of inactive galaxies. The AGN all lie in the redshift range 0.4<z<0.6. The accretion luminosity-density of the Universe peaks close to this redshift range, and the AGN in the sample have X-ray luminosities close to the knee in the hard X-ray luminosity function, making them representative of the population which dominated this important phase of energy conversion. Using both the spatial clustering amplitude and near neighbour counts it is found that the AGN have environments that are indistinguishable from normal, inactive galaxies over the same redshift range and with similar optical properties. Typically, the environments are of sub-cluster richness, in contrast to similar studies of high-z quasars, which are often found in clusters with comparable richness to the Abell R>=0 clusters. It is suggested that minor mergers with low mass companions is a likely candidate for the mechanism by which these modest luminosity AGN are fuelled.Comment: 12 pages, 6 figures, accepted by MNRA

Evidence of increased UV Fe II emission in quasars in candidate overdense regions

We present evidence for a skewed distribution of UV Fe ii emission in quasars within candidate overdense regions spanning spatial scales of ∼50 Mpc at 1.11 42 Å) and a dearth of low-equivalent-width sources. There are various possible explanations for this effect, including dust, Lyα fluorescence, microturbulence and iron abundance. We find that the most plausible of these is enhanced iron abundance in the overdense regions, consistent with an enhanced star formation rate in the overdense regions compared to the field

The effect of load and viscosity on the minimum operating oil film thickness of piston-rings in internal combustion engines

Computer simulations are now routinely used in the design and analysis of ring packs for internal combustion engines. Commonly they predict that an increase in engine load decreases minimum operating film thickness because oil availability and oil transport through the ring pack are reduced under these conditions. To assess the reliability of new simulations, investigators compare the output of computer models with experimental measurements of parameters on operating engines. Contributing to this process this paper presents an experimental study of an investigation into the effect of load on the minimum oil film thickness between piston rings and cylinder liner in a fired compression ignition engine. Oil film thickness data were collected using capacitance-based transducers located near top dead centre and mid-stroke. Experiments were performed at 2000 r/min using two mono-grade oils (SAE 50 and SAE 20) and one multi-grade oil (SAE 5W50) under a range of fixed engine loads. The experimental data obtained are discussed in the context of experimental and theoretical work published by other investigators
