Developing a rating scale for projected stories
The 6-Part Story Method (6PSM) is a projective tool in wide use by dramatherapists in the UK, USA and Israel (Lahad & Ayalon, 1993). In contrast to projective tests used by psychotherapists and psychologists, the 6PSM has never been the subject of any validation or reliability studies. This paper reports on the identification of scale items to describe the manifest content of 6-part stories. 26 statements with acceptable inter-rater reliability have been identified. These statements were used to rate stories produced by clinicians (n=24), mainstream community mental health patients (n=21) and patients with a Borderline Personality Disorder (n=19). Some features that were expected to be indicators of an author with a BPD diagnosis proved to be as common in stories from other authors. However a scale of eight items was identified that differentiated well between authors with a BPD diagnosis and others, with adequate test-retest and inter-rater reliability. Concurrent validity was tested against the Structured Clinical Interview for DSM-IV Axis II (SCID-II), the Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM) and the Inventory of Interpersonal Problems short form (IIP-32)
Renormalization effects on neutrino masses and mixing in a string-inspired SU(4) X SU(2)_L X SU(2)_R X U(1)_X model
We discuss renormalization effects on neutrino masses and mixing angles in a
supersymmetric string-inspired SU(4) X SU(2)_L X SU(2)_R X U(1)_X model, with
matter in fundamental and antisymmetric tensor representations and singlet
Higgs fields charged under the anomalous U(1)_X family symmetry. The quark,
lepton and neutrino Yukawa matrices are distinguished by different
Clebsch-Gordan coefficients. The presence of a second U(1)_X breaking singlet
with fractional charge allows a more realistic, hierarchical light neutrino
mass spectrum with bi-large mixing. By numerical investigation we find a region
in the model parameter space where the neutrino mass-squared differences and
mixing angles at low energy are consistent with experimental data.Comment: 9 pages, 7 figures; references adde
Cosmological frames for theories with absolute parallelism
The vierbein (tetrad) fields for closed and open Friedmann-Robertson-Walker
cosmologies are hard to work out in most of the theories featuring absolute
parallelism. The difficulty is traced in the fact that these theories are not
invariant under local Lorentz transformations of the vierbein. We illustrate
this issue in the framework of f(T) theories and Born-Infeld determinantal
gravity. In particular, we show that the early Universe as described by the
Born-Infeld scheme is singularity free and naturally inflationary as a
consequence of the very nature of Born-Infeld gravitational action.Comment: 8 pages, 1 figure. Talk given at the 8th Alexander Friedmann

Transcriptional Control: An Activating Role for Arginine Methylation
AbstractA rare histone modification, arginine methylation, has been linked to activation of hormone-responsive genes. Interestingly, methylation of a lysine residue in the same histone is present prior to hormone activation, but is excluded from the active loci
Comparing Segmentation by Time and by Motion in Visual Search: An fMRI Investigation
Abstract
Brain activity was recorded while participants engaged in a difficult visual search task for a target defined by the spatial configuration of its component elements. The search displays were segmented by time (a preview then a search display), by motion, or were unsegmented. A preparatory network showed activity to the preview display, in the time but not in the motion segmentation condition. A region of the precuneus showed (i) higher activation when displays were segmented by time or by motion, and (ii) correlated activity with larger segmentation benefits behaviorally, regardless of the cue. Additionally, the results revealed that success in temporal segmentation was correlated with reduced activation in early visual areas, including V1. The results depict partially overlapping brain networks for segmentation in search by time and motion, with both cue-independent and cue-specific mechanisms.</jats:p
Near-Independent Capacities and Highly Constrained Output Orders in the Simultaneous Free Recall of Auditory-Verbal and Visuo-Spatial Stimuli
Three experiments examined the immediate free recall (IFR) of auditory-verbal and visuospatial materials from single-modality and dual-modality lists. In Experiment 1, we presented participants with between 1 and 16 spoken words, with between 1 and 16 visuospatial dot locations, or with between 1 and 16 words and dots with synchronized onsets. We found that for dual-modality lists (a) overall performance, initial recalls, and serial position curves were largely determined by the within-modality list lengths, (b) there was only a small degree of dual-task trade-off (that was limited to the visuospatial items), and © there were strongly constrained output orders: participants tended to alternate between words and dots from equivalent or neighboring serial positions. In Experiments 2 and 3, we compared lists of 6 single-modality items with dual-modality lists of 6 words and 6 dots with synchronous or alternating onsets (Experiment 2), or random but asynchronous onsets (Experiment 3). In all 3 dual-modality conditions, we again found only a small trade-off in visuospatial (but not verbal) IFR performance. There were similarly highly constrained output orders with the synchronous and alternating onsets, and these patterns were present but attenuated with the randomized onsets. We propose that both auditory-verbal and visuospatial list items are associated with a common temporal episodic context that is used to guide cross-modal retrieval, and we speculate that the limited, asymmetric interference could arise because the less variable representations of the dots share only a relatively small subset of features with the more variable representations of the words
