On the convergent validity of two Parental Rearing Behaviour Scales: EIIBU and PBI

1999

The EMBU and PBI are two of the most used Parental Rearing Behaviour questionnaires. The literature assumes a high correlation between homonymous and assimilable factors (PBI Care and EMBU Affectional Warmth, PBI Control and EMBU Overprotection). Using a sample of 796 subjects the authors carried out the joint application of both scales in order to determine their concurrent validity. The correlation obtained between the scales barely reaches significance on average levels of correlation. The same can be deduced for the applied Multidimensional Scaling. In conclusion, the most extreme precaution is recommended when considering the homonymous scales of both questionnaires, and their joint us…

The relationship of symptom dimensions with premorbid adjustment and cognitive characteristics at first episode psychosis: Findings from the EU-GEI s…

2021

Premorbid functioning and cognitive measures may reflect gradients of developmental impairment across diagnostic categories in psychosis. In this study, we sought to examine the associations of current cognition and premorbid adjustment with symptom dimensions in a large first episode psychosis (FEP) sample. We used data from the international EU-GEI study. Bifactor modelling of the Operational Criteria in Studies of Psychotic Illness (OPCRIT) ratings provided general and specific symptom dimension scores. Premorbid Adjustment Scale estimated premorbid social (PSF) and academic adjustment (PAF), and WAIS-brief version measured IQ. A MANCOVA model examined the relationship between symptom di…

Assessing mentalization in psychotherapy: first validation of the Mentalization Imbalances Scale

2018

The aim of this study was to provide data on the preliminary validation of a clinician-report multidimensional assessment measure of mentalization (Mentalization Imbalances Scale, MIS). A random national sample of psychotherapists (N=190) completed the MIS to identify mentalization imbalances, and the Personality Disorder Checklist to assess the personality disorders (PDs) of randomly selected patients currently in their care. Factor analysis confirmed the presence of six factors that represented different imbalances of mentalization: cognitive, affective, automatic, external, imbalance toward others, and imbalance toward self. We found several significant relationships between patients’ me…

ICT adoption in hotels and electronic word-of-mouth

2015

Purpose The purpose of this paper is to investigate how information and communication technology (ICT) adoption in hotels contributes to satisfaction and loyalty from the consumer perspective, considering the online dimension of recommendations. Design/methodology/approach A quantitative research based on a structured questionnaire and using a personal survey method was developed. Surveys were conducted on 386 guests from Spanish hotels. Causal methodology by testing structural equation model was applied. Findings Significant relationships are obtained in the sequence “ICT use perception – satisfaction with ICT – overall satisfaction with the hotel – dimensions of loyalty” and the mediatin…

Role of geometry and anisotropic diffusion for modelling PO2 profiles in working red muscle

1990

A 3-dimensional analytical model of O2 diffusion in heavily working muscle is proposed which considers anisotropic, myoglobin (Mb)-facilitated O2 diffusion inside the muscle fiber and a carrier-free layer separating erythrocytes and fiber. The model is used to study the effects of some commonly applied simplifying assumptions (reduced dimensionality, neglected anisotropy) on the resulting PO2 distributions: (1) In order not to underestimate PO2 drops near erythrocytes, modelling O2 transport in 3 dimensions is important. (2) For a capillary-to-fiber ratio of 1, the results from the 2-dimensional version of the present model and from a Krogh-type model which incorporates a carrier-free layer…

Development and evaluation of 3-dimensional printed models of the human tracheobronchial system for training in flexible bronchoscopy.

2017

OBJECTIVES Training and assessment of proper skills in flexible bronchoscopy are major educational goals for cardiothoracic residents. Therefore, we developed 3-dimensional (3D) printed models of the human tracheobronchial system for training and assessment of cardiothoracic residents in flexible bronchoscopy. METHODS Three models of normal (size/shape) human tracheobronchial anatomy were generated using a commercially available 3D printer. Ten residents (inexperienced: Group 1; experienced: Group 2) participated in this study with an experimental setting of initial assessment (Model 1), training (15 min, Model 2) and post-training assessment (Model 3). The time needed for flexible bronchos…

Mitral valve annuloplasty and papillary muscle relocation oriented by 3-dimensional transesophageal echocardiography for severe functional mitral reg…

2012

Objective The study of the mitral valve apparatus and its modifications during functional mitral regurgitation (FMR) is better revealed by 3-dimensional (3D) transesophageal echocardiography (TOE). To plan mitral valve repair by annuloplasty and papillary muscle (PPM) relocation, we proposed a valve repair procedure oriented by the new main features obtained by real-time 3D TOE reconstruction of the mitral valve apparatus. Methods Since January 2008, 25 patients with severe FMR before mitral valve repair were examined. Mean coaptation depth and mean tenting area were 1.3 ± 0.2 cm and 3.2 ± 0.5 cm 2 , respectively. Intraoperative 2D and 3D TOE were performed, followed by a 3D offline reconst…

It has been shown in previous papers that classes of (minimal asymmetric) informationally-complete positive operator valued measures (IC-POVMs) in dimension d can be built using the multiparticle Pauli group acting on appropriate fiducial states. The latter states may also be derived starting from the Poincare upper half-plane model H . To do this, one translates the congruence (or non-congruence) subgroups of index d of the modular group into groups of permutation gates, some of the eigenstates of which are the sought fiducials. The structure of some IC-POVMs is found to be intimately related to the Kochen-Specker theorem.

Quantum Entanglement and the Issue of Selective Influences in Psychology: An Overview

2012

Similar formalisms have been independently developed in psychology, to deal with the issue of selective influences (deciding which of several experimental manipulations selectively influences each of several, generally non-independent, response variables), and in quantum mechanics (QM), to deal with the EPR entanglement phenomena (deciding whether an EPR experiment allows for a "classical" account). The parallels between these problems are established by observing that any two noncommuting measurements in QM are mutually exclusive and can therefore be treated as analogs of different values of one and the same input. Both problems reduce to that of the existence of a jointly distributed syst…
