    Grupos de especies asociadas en los moluscos Bentónicos de fondos duros del litoral catalán
    (Murcia: Universidad de Murcia, Servicio de Publicaciones, 1986) Ros Aragonés, Joandomènec; Facultad de Biología
    From the data of the PROGRAMA DE BENTOS (1972-74) samples, corresponding to six localities on the Catalan coast (Mediterranean Sea, hard substrates between O and 40 m in depth), the presence of groups of ecologically associated molluscan species is studied. Two methods have been used: a similarity index between species and a principal component analysis. Of the formed groups, some have a clear ecological or bionomic meaning, whereas others are not easy to interpret. The reduced number of species used in the analyses (only 56 of the total 189 in the similarity index, and only 21 in the principal component analysis) is the main factor blumng somewhat these results. The meaning of the obtained groups is discussed; they are also compared with the molluscan groups found in other studies: that of the benthos of Medes lslands (one of the previously studied localities), and of other Mediterranean littoral areas.

    Intentional vs. unintentional influences of social media friends
    (2020) Sicilia, María; Palazón, Mariola; López, Manuela; Comercialización e Investigación de Mercados
    On social media, individuals’ behavior can be affected as a result of either direct and intended recommendations by social media friends, or unintentional brand-related actions developed by social media friends. This study addresses the differences between intentional and unintentional influences by testing a model that delineates similarity and tie strength as drivers of influence, and purchase intention and social media engagement as the main outcomes. Based on the elaboration likelihood model, we analyze the underlying mechanism of unintentional influences versus intentional ones by comparing the role of source usefulness and information usefulness in the two influential processes. Results of two studies show that individuals can be unintentionally influenced by their social media friends, and the effect is similar to that from intentional influences. However, different mechanisms seem to be involved in the two influential processes. A central route of processing seems to be the mechanism underlying intentional influence, whereas both central and peripheral routes are used when the influence is unintentional.

    Las oraciones impersonales: un análisis comparativo español-italiano
    (2015-12-03) Giordano, Roberta
    One of the most complex aspects of Spanish syntax is represented by impersonal sentences. The effort to carry out a Spanish-Italian contrastive analysis of these sentences represents a possible answer to the challenge, for teachers of Spanish as a foreign language, of transmitting these expressions to Italian speaking students. In developing our discussion, we start from two interpretative proposals: that of José Joaquín Montes Giraldo, "Frase nominal, frase verbal y enunciados impersonales" (Thesaurus, XLI, 1986), and that of Luis Alberto Hernando Cuadrado, "Sobre la expresión de la impersonalidad" (Proceedings of the IV ASELE Congress, 1994).
