Belnap-Dunn Semantics for the Variants of BN4 and E4 which Contain Routley and Meyer’s Logic B

The logics BN4 and E4 can be considered as the 4-valued logics of the relevant conditional and (relevant) entailment, respectively. The logic BN4 was developed by Brady in 1982 and the logic E4 by Robles and Méndez in 2016. The aim of this paper is to investigate the implicative variants (of both systems) which contain Routley and Meyer’s logic B and endow them with a Belnap-Dunn type bivalent semantics

A 2-set-up Routley-Meyer Semantics for the 4-valued Relevant Logic E4

The logic BN4 can be considered as the 4-valued logic of the relevant conditional and the logic E4, as the 4-valued logic of (relevant) entailment. The aim of this paper is to endow E4 with a 2-set-up Routley-Meyer semantics. It is proved that E4 is strongly sound and complete w.r.t. this semantics

Selecting the Class of All 3-Valued Implicative Expansions of Kleene's Strong Logic Containing Routley and Meyer's Logic B

We define all implicative expansions of Kleene's strong 3-valued matrix (with both only one and two designated values) verifying Routley and Meyer's basic logic B. Then, the logics determined by each one of these implicative expansions are axiomatized by using a Belnap-Dunn "two-valued" semantics. This semantics is "overdetermined" in the case of two designated values, and "underdetermined" when there is only one.SIMinisterio de Economía, Industria y Competitivida

Relational Semantics for the Paraconsistent and Paracomplete 4-valued Logic PŁ4

The paraconsistent and paracomplete 4-valued logic PŁ4 is originally interpreted with a two-valued Belnap-Dunn semantics. In the present paper, PŁ4 is endowed with both a ternary Routley-Meyer semantics and a binary Routley semantics together with their respective restriction to the 2 set-up cases

Ternary Relational Semantics for the Variants of BN4 and E4 which Contain Routley and Meyer's Logic B

Six interesting variants of the logics BN4 and E4—which can be considered as the 4-valued logics of the relevant conditional and (relevant) entailment, respectively—were previously developed in the literature. All these systems are related to the family of relevant logics and contain Routley and Meyer's basic logic B, which is well-known to be specifically associated with the ternary relational semantics. The aim of this paper is to develop reduced general Routley-Meyer semantics for them. Strong soundness and completeness theorems are proved for each one of the logics

THE RELATIONSHIP BETWEEN LEVEL OF EDUCATION, ORGANIZATIONAL COMMITMENT AND JOB SATISFACTION: AN ANALYSIS IN HOTEL ESTABLISHMENTS IN ANDALUSIA (SPAIN)

Nisu svi zaposlenici sposobni generirati vještine i resurse kojima bi se ostvarila organizacijska produktivnost. Samo su kvalificirani ljudski resursi (HR), prepo¬znati i odani politici tvrtke, dio organizacijskih kompetencija. Stoga su čimbenici zadovoljstva zapo¬slenika radom te predanost tvrtki dvije ključne varijable koje moramo analizirati kako bismo ispravno procijenili i pravilno upravljali ljudskim kapitalom tvrtke. Posebno se velika važnost pridaje vrijed¬nosti obrazovanja zaposlenika u svjetlu konkurentnosti turizma, što je u skladu s pretpostavkom kako stupanj obrazovanja zaposlenika izravno utječe na kvalitetu turističkih usluga. Cilj je ovog članka analizirati zadovoljstvo radnim mjestom i organizacijske obveze zaposlenika hotelskih kuća u Andaluziji (Španjolska), destinaciji čija je nesumnjiva konkurentska važnost u turi¬zmu neupitna. Pronađene su evidentne razlike u stupnju obrazovanja zaposlenika, tako da rezultati svakako ohrabruju odjele upravljanja ljudskim resursima na identifikaciju, održavanje i razvoj resursa i potencijalnih sposobnosti njihovog ljudskog kapitala.Not all employees are capable of generating skills and resources that may result in organizational productivity. Only qualified Human Resources, identified and committed to the company policy, are a part of the organization\u27s competences. Therefore, elements like the worker\u27s job satisfaction or the organizational commitment are two fundamental variables that need to be analyzed for the measurement and correct management of the company\u27s human capital. Further¬more, the importance that the value of the workers\u27 education presents towards competitiveness in tourism is highlighted since it is assumed that staff education is directly related to the quality of tourist service. The purpose of this paper is to analyze the relationship among educational level, job satisfaction, and organizational commitment of the employees of the hotel establishments in Andalusia (Spain), a destination of undeniable competitive significance in tourism. Evident differences were found among the level of education of workers, so the results have to encourage the human resources management to identify, maintain, and develop the resources and potential capabilities of their human capital

Veinte años de producción científica en psicología en la Universidad Católica de Colombia: análisis bibliométrico de la investigación publicada (1983 - 2002)

Se presenta un detallado análisis bibliométrico de los artículos producto de la actividad científica de la Facultad de Psicología de la Universidad Católica de Colombia publicados desde 1983 hasta el 2002. Se revisaron las tres principales bases de datos Psicodoc, PsycInfo, PsycLit, además de una revisión directa en revistas de Psicología y Ciencias afines. A partir de los artículos encontrados se construyó una base de datos, que incluía autor o autores, otras instituciones con quien se publicó, áreas de investigación, lugar de publicación, tipo de publicación, modalidad y fuente donde fue encontrado. En resumen se encontró lo siguiente: setenta y dos artículos en catorce revistas, nueve de ellas internacionales y cinco nacionales, de las cuales en aproximadamente once de las catorce, es decir, el 78.57% se encuentra incluida en alguna base de datos o índice internacional, sin embargo un 79.16% de los artículos encontrados se encuentran concentrados en revistas nacionales, y solo el 20.83% en las internacionales. Un 43% de los artículos fueron escritos por mas de un autor lo que muestra una importante producción en grupo y el 57 % es producto de actividad individual y por autores que no repitieron, es importante también reseñar que algunos autores jalonan la producción general, es así como cinco autores concentran el 35 % del total el 65% restante escribió entre uno y dos artículos el área de mayor trabajo es la clínica seguida por la básica y la educativa y el 71 % de la misma se concentra en los últimos cinco años y aquí es claro el papel tan relevante que ha tenido la publicación de la revista en la producción de artículos el 51 % se han publicado en Acta Colombiana De Psicología.A detailed bibliometric analysis is presented of the articles product of the scientific activity of the Psychology Department at the Catholic University between 1983 to 2002. In this order the Psicodoc, PsycInfo, PsycLit databases were revised, besides other psychological and related science journals. The collected data included for each article: author (s), other institution that supported, year, place, type of publication, modality and source where was found. The results showed: The production of 72 published articles in 14 journal (nine international and five Colombian), of which in approximately eleven of the fourteen, that is to say, the 78.6% is found included in data base or international index, nevertheless 79% of the articles found are concentrated in colombian journals, and 20.83% in the international journals. 43% of the articles were written by but of an author what shows an important production in group and 57% is individual product of activity and by authors that did not repeat. Is important also show that some authors mark the general production, is as well as five authors concentrate 35% of the total. 65% remainder wrote between one and two articles. Finally, the most production areas, in order, were clinical, basic and educative. and 71% of the same one concentrates on the last five years and here is clear the so prominent role that has had the publication of the magazine in the production of articles 51% have been published in Acta Colombiana de Psicología

Relational semantics for the 4-valued relevant logics BN4 and E4

The logic BN4 was defined by R.T. Brady in 1982. It can be considered as the 4-valued logic of the relevant conditional. E4 is a variant of BN4 that can be considered as the 4-valued logic of (relevant) entailment. The aim of this paper is to define reduced general Routley-Meyer semantics for BN4 and E4. It is proved that BN4 and E4 are strongly sound and complete w.r.t. their respective semantics

Una experiencia piloto de aplicación del inglés en los estudios de Turismo y Empresariales de la Universidad de Córdoba

El coneixement de la llengua anglesa és bàsica en qualsevol titulació universitària, amb molta importància en els estudis de Turisme i Empresarials. Durant els cursos 2007-08 i 2008-2009 s’ha realitzat una experiència pilot en diferents assignatures d’ambdues titulacions amb l’objectiu de que els estudiants comprenguin la importància de l’anglès com element bàsic en la seva carrera professional. Per aquest motiu, i utilitzant la plataforma Moodle, s’ha construït una experiència on l’alumnat ha desenvolupat diferents activitats emmarcades en diferents nivells d’aprenentatge de l’ idioma. L’objectiu és que paulatinament s’arribés a conèixer, assimilar i definir en anglès els conceptes més importants relacionats amb els continguts acadèmics vistos en les assignatures.The knowledge of the English language is essential in any university degree, especially in Tourism and Business Studies.
