Comment on "Electron transport through correlated molecules computed using the time-independent Wigner function: Two critical tests"

The many electron correlated scattering (MECS) approach to quantum electronic transport was investigated in the linear response regime [I. Baldea and H. Koeppel, Phys. Rev. B. 78, 115315 (2008)]. The authors suggest, based on numerical calculations, that the manner in which the method imposes boundary conditions is unable to reproduce the well-known phenomena of conductance quantization. We introduce an analytical model and demonstrate that conductance quantization is correctly obtained using open system boundary conditions within the MECS approach.Comment: 18 pages, 4 figures.

Validating the Use of Vignettes for Subjective Threshold Scales

Comparing self-assessed indicators of subjective outcomes such as health, work disability, political efficacy, job satisfaction, etc. across countries or socio-economic groups is often hampered by the fact that different groups use systematically different response scales. Anchoring vignettes have been introduced as an effective tool to correct for such differences. This paper develops an integrated framework in which objective measurements are used to validate the vignette-based corrections. The framework is applied to vignettes and objective and subjective self-assessments of drinking behavior by students in Ireland. Model comparisons using the Akaike information criterion favor a specification with response consistency and vignette corrected response scales. Put differently, vignette based corrections appear quite effective in bringing objective and subjective measures closer together.anchoring vignettes;reporting bias;hopit model

This report aims to provide 139 Local Governments in urban and semi urban environments across Australia with an estimate of land surface cover. This study is part of the 202020 Vision, funded by Horticulture Limited Australia, in working towards a 20% increase in the level of green space in Local Government Areas (LGAs) across the country.

Preliminary design study of a quiet, high flow fan (QHF) stage

Concepts selected to reduce fan generated noise in a turbofan are presented. Near-sonic flow at the fan inlet to reduce upstream propagated noise and the use of long-chord vanes to reduce downstream noise is discussed. The near-sonic condition at the rotor inlet plane was achieved by designing for high specific mass flow and by maintaining the high flow at reduced power by variable stators and variable fan exhaust nozzle. The long-chord vanes reduce response to unsteady flow. The acoustic design showed that long-chord stators would significantly reduce turbofan source noise and that other stator design parameters have no appreciable effect on noise for the spacing and chord length of the turbofan design. Four rig flow paths studied in the aerodynamic preliminary design are discussed. Noise prediction results indicate that a turbofan powered aircraft would be under federal air regulations levels without any acoustic treatment

La psychothérapie focalisée sur le transfert

La psychothérapie focalisée sur le transfert (PFT) est une version modifiée de la psychothérapie psychodynamique classique et spécialisée pour les troubles graves de la personnalité. Elle se fonde sur les principes de la psychanalyse et sur la théorie des relations objectales. L’organisation du monde psychique se structure à partir de l’expérience des interrelations personnelles impliquant une pulsion venant buter contre un objet et produisant un affect agréable ou désagréable. L’expérience ainsi vécue structure une dyade relationnelle impliquant une représentation de Soi et une représentation de l’autre liées par l’affect éprouvé. Par la suite, les représentations s’intègrent les unes aux autres pour former un monde interne évolué, souple, dynamique, adaptée à la réalité externe ou, au contraire, un monde primitif, rigide et fréquemment en conflit avec la réalité externe. La psychothérapie focalisée sur le transfert se propose justement de faire évoluer la structure de la personnalité par le biais d’une analyse soutenue de l’expérience relationnelle vécue avec le psychothérapeute, la mise à jour des représentations de soi et de l’autre et de l’affect qui les lie et la prise de conscience des désirs et motifs inconscients de la personne. Une phase de diagnostic différentiel par le biais d’une entrevue structurale et l’élaboration d’un contrat psychothérapique précède la psychothérapie proprement dite. Le premier but de la psychothérapie focalisée sur le transfert est d’engager la personne dans une observation et une prise de conscience des représentations d’elle-même et des autres. Ces représentations sont le plus souvent biaisées par l’organisation inconsciente du monde interne.Transference focused psychotherapy is a version of psychodynamic psychotherapy that is modified and specialized for patients with borderline personality disorder. It is based on psychoanalytic principles with an emphasis on object relations theory. A fundamental concept in this model is that the organization of an individual’s psyche is structured around internalized versions of interpersonal relations. The relationship experiences that are internalized involve a specific representation of the self, a specific representation of the other (the object of the libidinal or aggressive drive) and an intense affect that links them. However, this movement toward integration of the internal representational world does not take place in individuals with borderline personality, who continue to experience life in a way that is based on rigid and extreme views of self and others. The goal of transference focused psychotherapy is to help individuals advance to an integrated internal world through the analysis of the patient’s ongoing experience of his or her relationship with the therapist. It is assumed that the analysis of this relationship will bring to light the internal representations of self and other, and the corresponding affects, that are related to unconscious desires and motivations, and that underlie the individual’s extreme and discontinuous experience in life. The therapy begins with a specific diagnostic interview and the establishment of a treatment contract with the patient before the psychotherapeutic work begins. The first goal of the therapy is to engage the patient in the process of observing and gaining awareness of the representations of self and other that guide his or her perceptions of the world. The therapy then helps the patient to understand the internal forces that have kept theses representations segregated from each other and to integrate them into a more mature and coherent sense of self and others.La psicoterapia focalizada en la transferencia (PFT) es una versión modificada de la psicoterapia psicodinámica clásica y especializada para los trastornos graves de la personalidad.

Porous silica spheres as indoor air pollutant scavengers

Porous silica spheres were investigated for their effectiveness in removing typical indoor air pollutants, such as aromatic and carbonyl-containing volatile organic compounds (VOCs), and compared to the commercially available polymer styrene-divinylbenzene (XAD-4). The silica spheres and the XAD-4 resin were coated on denuder sampling devices and their adsorption efficiencies for volatile organic compounds evaluated using an indoor air simulation chamber. Real indoor sampling was also undertaken to evaluate the affinity of the silica adsorbents for a variety of indoor VOCs. The silica sphere adsorbents were found to have a high affinity for polar carbonyls and found to be more efficient than the XAD-4 resin at adsorbing carbonyls in an indoor environment
