On the Asserted Clash between the Freud and the Bianchi Identities

Through a constructive method it is shown that the claim advanced in recent times about a clash that should occur between the Freud and the Bianchi identities in Einstein's general theory of relativity is based on a faulty argument.Comment: 4 pages, plain Te

Covariance properties and regularization of conserved currents in tetrad gravity

We discuss the properties of the gravitational energy-momentum 3-form within the tetrad formulation of general relativity theory. We derive the covariance properties of the quantities describing the energy-momentum content under Lorentz transformations of the tetrad. As an application, we consider the computation of the total energy (mass) of some exact solutions of Einstein's general relativity theory which describe compact sources with asymptotically flat spacetime geometry. As it is known, depending on the choice of tetrad frame, the formal total integral for such configurations may diverge. We propose a natural regularization method which yields finite values for the total energy-momentum of the system and demonstrate how it works on a number of explicit examples.Comment: 36 pages, Revtex, no figures; small changes, published versio

On creating mass/matter by extra dimensions in the Einstein-Gauss-Bonnet gravity

Kaluza-Klein (KK) black hole solutions in the Einstein-Gauss-Bonnet (EGB) gravity in $D$ dimensions obtained in the current series of the works by Maeda, Dadhich and Molina are examined. Interpreting their solutions, the authors claim that the mass/matter is created by the extra dimensions. To support this claim, one needs to show that such objects have classically defined masses. We calculate the mass and mass flux for 3D KK black holes in 6D EGB gravity whose properties are sufficiently physically interesting. Superpotentials for arbitrary types of perturbations on arbitrary curved backgrounds, recently obtained by the author, are used, and acceptable mass and mass flux are obtained. A possibility of considering the KK created matter as dark matter in the Universe is discussed.Comment: 15 pages, no figures, minor changes related to the Journal publication with adding two references in footnote

Currents and Superpotentials in classical gauge invariant theories I. Local results with applications to Perfect Fluids and General Relativity

E. Noether's general analysis of conservation laws has to be completed in a Lagrangian theory with local gauge invariance. Bulk charges are replaced by fluxes of superpotentials. Gauge invariant bulk charges may subsist when distinguished one-dimensional subgroups are present. As a first illustration we propose a new {\it Affine action} that reduces to General Relativity upon gauge fixing the dilatation (Weyl 1918 like) part of the connection and elimination of auxiliary fields. It allows a comparison of most gravity superpotentials and we discuss their selection by the choice of boundary conditions. A second and independent application is a geometrical reinterpretation of the convection of vorticity in barotropic nonviscous fluids. We identify the one-dimensional subgroups responsible for the bulk charges and thus propose an impulsive forcing for creating or destroying selectively helicity. This is an example of a new and general Forcing Rule.Comment: 64 pages, LaTeX. Version 2 has two more references and one misprint corrected. Accepted in Classical and Quantum Gravit

Some comments on the significance and development of midline behavior during infancy

With the waning of the tonic neck reflex beginning with the 8th to 12th week, and disappearing, in most instances, by the 16th week, the infant begins to become bilateral and makes symmetrical movements and engages his hands in the midline usually over the chest while in a supine position. The developmental significance of such behavior is considered—for example, its participation in the emerging sense of self and its role in the consolidation of emerging ego skills. Consideration is given to the possible implications of faulty midline behavior for development, and to whether failure to engage in an optimal amount of midline behavior, in interaction with other factors, can be used to alert observers to possible future developmental disturbances.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43965/1/10578_2005_Article_BF01435498.pd

Expanding the role of supervision in child psychiatric education

Despite the burgeoning of available therapeutic interventions, the sparse literature devoted to child psychiatric supervision concentrates on individual psychotherapy. The non-cognitive aspects of the expanding supervisory challenge continues to converge on the clinician's personality, which is a focus of educational attention only in sequestered or haphazard parts of programs. The unidimensional supervisory literature addresses this issue by questioning the extent to which supervision should resemble traditional pedagogy or personal psychotherapy. In contrast to this emphasis on elusive unconscious influences on clinical work, scant attention has been devoted to other influences stemming from the clinician's current experiences, affiliations, identifications, aspirations and similar more easily modifiable factors that exert considerable leverage and tend to be more accessible to rational scrutiny in supervision. The latter half of this paper discusses these factors.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43974/1/10578_2005_Article_BF01463219.pd

Outcome of crisis intervention for borderline personality disorder and post traumatic stress disorder: a model for modification of the mechanism of disorder in complex post traumatic syndromes

<p>Abstract</p> <p>Background</p> <p>This study investigates the outcome of crisis intervention for chronic post traumatic disorders with a model based on the theory that such crises manifest trauma in the present. The sufferer's behavior is in response to the current perception of dependency and entrapment in a mistrusted relationship. The mechanism of disorder is the sufferer's activity, which aims to either prove or disprove the perception of entrapment, but, instead, elicits more semblances of it in a circular manner. Patients have reasons to keep such activity private from therapy and are barely aware of it as the source of their symptoms.</p> <p>Methods</p> <p>The hypothesis is that the experimental intervention will reduce symptoms broadly within 8 to 24 h from initiation of treatment, compared to treatment as usual. The experimental intervention sidesteps other symptoms to engage patients in testing the trustworthiness of the troubled relationship with closure, thus ending the circularity of their own ways. The study compares 32 experimental subjects with 26 controls at similar crisis stabilization units.</p> <p>Results</p> <p>The results of the Brief Psychiatric Rating Scale (BPRS) supported the hypothesis (both in total score and for four of five subscales), as did results with Client Observation, a pilot instrument designed specifically for the circular behavior targeted by the experimental intervention. Results were mostly non-significant from two instruments of patient self-observation, which provided retrospective pretreatment scores.</p> <p>Conclusions</p> <p>The discussion envisions further steps to ascertain that this broad reduction of symptoms ensues from the singular correction that distinguishes the experimental intervention.</p> <p>Trial registration</p> <p>Protocol Registration System NCT00269139.

An Integrative-Relational Approach in Schizophrenia: From Philosophical Principles to Mentalization-Based Practice

In this paper, we explore psychosis and schizophrenia as prototype disturbances, where mentalizing failures are widely seen. We attempt to describe how the process of rekindling mentalizing within attachment relationships (here, the patient-therapist relationship) can have a protective effect not just on the onset of the disturbance, but also when psychosis is already actively installed. We start by discussing mentalizing in training, practice and supervision. We also try to understand it contextually, as a relational concept, within the history of psychological therapies
