Addressing neuroticism in psychological treatment

Neuroticism has long been associated with psychopathology and there is increasing evidence that this trait represents a shared vulnerability responsible for the development and maintenance of a range of common mental disorders. Given that neuroticism may be more malleable than previously thought, targeting this trait in treatment, rather than its specific manifestations (e.g., anxiety, mood, and personality disorders), may represent a more efficient and cost-effective approach to psychological treatment. The goals of the current manuscript are to (a) review the role of neuroticism in the development of common mental disorders, (b) describe the evidence of its malleability, and (c) review interventions that have been explicitly developed to target this trait in treatment. Implications for shifting the focus of psychological treatment to underlying vulnerabilities, such as neuroticism, rather than on the manifest symptoms of mental health conditions, are also discussed.First author draf

Millimeter Imaging of MWC 758: Probing the Disk Structure and Kinematics

We investigate the structure and kinematics of the circumstellar disk around the Herbig Ae star MWC 758 using high-resolution observations of the ^(12)CO (3-2) and dust continuum emission at the wavelengths of 0.87 and 3.3 mm. We find that the dust emission peaks at an orbital radius of about 100 AU, while the CO intensity has a central peak coincident with the position of the star. The CO emission is in agreement with a disk in Keplerian rotation around a 2.0 M_⊙ star, confirming that MWC 758 is indeed an intermediate-mass star. By comparing the observation with theoretical disk models, we derive that the disk surface density Σ(r) steeply increases from 40 to 100 AU and decreases exponentially outward. Within 40 AU, the disk has to be optically thin in the continuum emission at millimeter wavelengths to explain the observed dust morphology, though our observations lack the angular resolution and sensitivity required to constrain the surface density on these spatial scales. The surface density distribution in MWC 758 disk is similar to that of "transition" disks, though no disk clearing has been previously inferred from the analysis of the spectral energy distribution (SED). Moreover, the asymmetries observed in the dust and CO emission suggest that the disk may be gravitationally perturbed by a low-mass companion orbiting within a radius of 30 AU. Our results emphasize that SEDs alone do not provide a complete picture of disk structure and that high-resolution millimeter-wave images are essential to reveal the structure of the cool disk mid-plane
