The relationship between vegetation and modern pollen assemblages on Mount Paggeo (NE Greece)

In this study, we investigated the relationship between vegetation and modern-pollen rain along the elevational gradient of Mount Paggeo. We apply multivariate data analysis to assess the relationship between vegetation and modern-pollen rain and quantify the representativeness of forest zones. This study represents the first statistical analysis of pollen-vegetation relationship along an elevational gradient in Greece. Hence, this paper improves confidence in interpretation of palynological records from north-eastern Greece and may refine past climate reconstructions for a more accurate comparison of data and modelling. Numerical classification and ordination were performed on pollen data to assess differences among plant communities that beech (Fagus sylvatica) dominates or co-dominates. The results show a strong relationship between altitude, arboreal cover, human impact and variations in pollen and nonpollen palynomorph taxa percentages.

Mental logic and its difficulties with disjunction

The mental logic theory does not accept the disjunction introduction rule of standard propositional calculus as a natural schema of the human mind. In this way, the problem that I want to show in this paper is that, however, that theory does admit another much more complex schema in which the mentioned rule must be used as a previous step. So, I try to argue that this is a very important problem that the mental logic theory needs to solve, and claim that another rival theory, the mental models theory, does not have these difficulties.

Causatividad y construcciones con verbo soporte en latín: el ejemplo de "poena afficere"

En este trabajo nos proponemos analizar la colocación latina poena afficere, ‘imponer un castigo’, un tipo de colocación con especificidades tanto sintácticas como semánticas que la distinguen de las construcciones verbo-nominales más prototípicas: el sustantivo predicativo funciona no como Objeto Directo sino como tercer argumento del verbo soporte, un esquema sintáctico que, como intentaremos demostrar, resulta ideal para la expresión de predicados causativos. De los ejemplos documentados de poena afficere en un amplio corpus de textos, intentaremos destacar las principales características de este tipo de colocación. Para su descripción y formalización nos serviremos del marco teórico propuesto por la Teoría Sentido-Texto.
