New Encodings of Pseudo-Boolean Constraints into CNF
2009
International audience; This paper answers affirmatively the open question of the existence of a polynomial size CNF encoding of pseudo-Boolean (PB) constraints such that generalized arc consistency (GAC) is maintained through unit propagation (UP). All previous encodings of PB constraints either did not allow UP to maintain GAC, or were of exponential size in the worst case. This paper presents an encoding that realizes both of the desired properties. From a theoretical point of view, this narrows the gap between the expressive power of clauses and the one of pseudo-Boolean constraints.
The Consistency of Fairness Rules: An Experimental Study
2010
In the last two decades, experimental papers on distributive justice have abounded. Two main results have been replicated. Firstly, there is a multiplicity of fairness rules. Secondly, fairness decisions differ depending on the context. This paper studies individual consistency in the use of fairness rules, as well as the structural factors that lead people to be inconsistent. We use a within-subject design, which allows us to compare individual behavior when the context changes. In line with the literature, we find a multiplicity of fairness rules. However, when we control for consistency, the set of fairness rules is considerably smaller. Only selfishness and strict egalitarianism seem to…
Latest technology and communication consistency in hospitality: a comparison between two Mediterranean countries
2016
AbstractThe goal of this research is to examine customers′ perceptions of the latest technology solutions and marketing communications within the hotel context in two Mediterranean countries – Croatia and Italy. In particular, hotel guests of four- and five-star hotels located in these countries participated in the research. Firstly, guest perceptions of advanced Information and Communication Technology (ICT) and communication consistency are analysed and compared in Croatian and Italian hotels. Secondly, the impact of ICT on communication consistency is tested in both studies. The findings show that the level of customer perceptions of communication consistency is relatively high in both c…
Validación de un Cuestionario Multidimensional de Adaptación a la Enfermedad para Pacientes Renales en Diálisis (CMAE-RD) diseñado a partir de un cue…
2020
espanolObjetivos: El objetivo de este trabajo es estudiar las propiedades psicometricas de un cuestionario multidimensional de adaptacion a la enfermedad para pacientes con enfermedad renal en dialisis (CMAE-RD).Metodos: Esta herramienta esta disenada para ser administrada por un profesional de la psicologia en forma de entrevista semiestructurada y fue disenado a partir de un cuestionario previo para pacientes oncohematologicos. Un total de 113 pacientes en hemodialisis fueron entrevistados mediante el CMAE-RD y completaron dos cuestionarios adicionales con propositos de validacion: el HADS (para evaluar ansiedad y depresion) y el CDRISC-2 (para evaluar resiliencia).Resultados: La consiste…
Educación XX1 : revista de la Facultad de Educación
2017
Introducción: La institucionalización del Aprendizaje-Servicio (ApS) en la universidad recomienda, en primer lugar, el análisis de la cultura docente del profesorado y su actitud hacia la innovación. Precisamente, lo que este trabajo pretende es aportar un modelo teórico integrador desarrollando tres escalas de evaluación, contrastadas a través de pruebas estadísticas, para el contexto de la enseñanza universitaria en España. Metodología: A fin de elaborar el modelo de medida se aplicaron tres escalas a 1903 profesoras y profesores de 6 universidades españolas: una escala de práctica docente (18 ítems), otra sobre compromiso social de la Universidad (9 ítems), y una tercera, sobre prácticas…
Psychometric Properties and Convergent Validity of the Dependency-Oriented and Achievement-Oriented Psychological Control Scale (DAPCS) with Italian …
2013
This study is aimed to validate the Italian version of the dependency-oriented and achievement-oriented psychological control scale (DAPCS), a self-report questionnaire designed to assess the adolescent’s perception of the two dimensions of psychological control. In Study 1, we assessed factorial validity and reliability of the Italian version of DAPCS with a sample of adolescents. In Study 2, we examined the convergent validity of the Italian version of the DAPCS analyzing the associations between the two domains of psychological control and well-established measures related to them such as strictness/supervision, overprotection, non dependency on parents, and family functioning. Confirmat…
VALIDACIÓN EN CONTEXTO ESPAÑOL DE LA SUBPRUEBA DE INICIO DE LA ESCRITURA DE LA SHELL
2016
Abstract:VALIDATION IN THE SPANISH CONTEXT OF SHELL’S SUBTEST OF EMERGENT WRITING SKILLSBecause of a lack of research examining early learning skills involved in writing and, above all, the lack of tests evaluating it, the main objective of this work is the validation in the spanish context of SHELL’s subscales related to emergent writing skills. Participants were 119 students from the provinces of Castellón and Valencia, who have been evaluated when 4 years old. The administered instrument was a spanish version of the subtests related to early writing of SHELL scale in which the child has to choose between some letters, the one he needs to write some words (his/her name, “sea”, “sun”, “whi…
Il Rilievo MMS di tracciati autostradali
2009
Già da alcuni anni alcuni autori hanno messo in risalto come, anche in ambito autostradale, la geometria d’asse intesa come il complesso plano-altimetrico degli elementi di tracciato, eserciti un ruolo non marginale sulla condotta di guida dell’utente. Grazie alle metodologie di verifica della coerenza della linea d’asse di tracciato (Design Consistency), si accerta o meno che esista un’armonica correlazione tra parametri geometrici significativi e la velocità, di progetto od operativa, del tronco considerato. L’espressione grafica di tale correlazione è il cosiddetto diagramma delle velocità, dalla cui analisi, secondo criteri invero peculiari di infrastrutture viarie non autostradali, è p…
Levels of self-consistency in the GW approximation
2009
We perform $GW$ calculations on atoms and diatomic molecules at different levels of self-consistency and investigate the effects of self-consistency on total energies, ionization potentials and on particle number conservation. We further propose a partially self-consistent $GW$ scheme in which we keep the correlation part of the self-energy fixed within the self-consistency cycle. This approximation is compared to the fully self-consistent $GW$ results and to the $G W_0$ and the $G_0W_0$ approximations. Total energies, ionization potentials and two-electron removal energies obtained with our partially self-consistent $GW$ approximation are in excellent agreement with fully self-consistent $…
Dimensions underlying frailty indicators in the Kihon Checklist.
2019
Aim Frailty has become a current topic of debate in recent years among researchers as a key concept of clinical care in old age. One of the scales developed for its measurement is the Kihon Checklist (KCL). However, the dimensionality of the KCL has not been tested yet, and therefore the aim of the present study was to validate its dimensional structure. Methods This was a cross-sectional study carried out between March and September 2018 in Valencia province (Spain). Participation in the study was voluntary. A total of 251 participants were sampled. They answered sociodemographic and medical indicators, as well as five frailty scales, including the KCL. Results Five confirmatory models wit…
