A Fuzzy Logic Programming Environment for Managing Similarity and Truth Degrees

FASILL (acronym of "Fuzzy Aggregators and Similarity Into a Logic Language") is a fuzzy logic programming language with implicit/explicit truth degree annotations, a great variety of connectives and unification by similarity. FASILL integrates and extends features coming from MALP (Multi-Adjoint Logic Programming, a fuzzy logic language with explicitly annotated rules) and Bousi~Prolog (which uses a weak unification algorithm and is well suited for flexible query answering). Hence, it properly manages similarity and truth degrees in a single framework combining the expressive benefits of both languages. This paper presents the main features and implementations details of FASILL. Along the paper we describe its syntax and operational semantics and we give clues of the implementation of the lattice module and the similarity module, two of the main building blocks of the new programming environment which enriches the FLOPER system developed in our research group.Comment: In Proceedings PROLE 2014, arXiv:1501.0169

Microhistory of a Microscopic Society: An Approximation to the Jesuit Mission of the Upper Napo (Ecuador), 1870-1896

El presente estudio representa una reevaluación de la historia jesuita en el Alto Napo ecuatoriano a finales del siglo XIX y principios del XX. Se trata de una mirada micro-histórica a las relaciones socioeconómicas existentes entre religiosos, indígenas, mercaderes y autoridades civiles, en una época de grandes transformaciones –tanto en Ecuador como en la Amazonía. El artículo está basado en fuentes primarias, publicadas y de archivo, muchas de las cuales no han sido estudiadas hasta la fecha.This study represents a re-evaluation of the Jesuit experience in the Upper Napo of Ecuador at the turn of the twentieth century. The article is a micro-historical approach to the links that existed between Jesuits, Indians, merchants and civil authorities, in a time of great transformations –both in Ecuador and in the Amazon. This research is based on primary sources, published as well as archival, many of which have not been studied to this day

Seasonal decline in breeding performance of the Kelp Gull Larus dominicanus

The effects of timing of breeding on reproductive parameters of Kelp Gulls Larus dominicanus were studied in Patagonia, Argentina, during 1998 and 1999. Yearly and spatial variation in the study were assessed by sampling nests during two field seasons and in different areas within the colony, and accounted for variation with respect to breeding synchrony and breeding density. In both years and in three study areas, individuals laying earlier had higher hatching success, a larger number of chicks fledged, heavier chicks at one month and higher breeding success. Significant variation between study areas within the colony and between years was observed only for breeding success and number of chicks fledged. No effects of breeding synchrony on breeding parameters were detected. Timing of breeding, independent of study year and area, had no effect on either clutch size or egg size. Our results document for the first time the seasonal decline in breeding performance in the Kelp Gull, a species widely distributed in the southern hemisphere.Fil: Garcia Borboroglu, Jorge Pablo.
