The purpose of this work is to recapture the life and work of the Brazilian scientist Antônio Lopes de Sá, as well as his thinking on accounting science. To this end, we present the relationships of the historical and scientific elements of Auguste Comte's positive theory, the objective elements forming Durkheim's social fact, and Vilfredo Pareto's logical actions and Lopes' logical reasoning. The method used was descriptive, with a qualitative approach and from bibliographic documentary sources. The objective of this exercise was to verify whether Lopes' work, based on these principles, is innovative from a conceptual accounting point of view. It is concluded that his work is foundational and innovative in various aspects, especially in regards to the scientific autonomy of the object of study of accounting. [ABSTRACT FROM AUTHOR]

We present an approach to abductive reasoning on C-structures, that is, structures with a finite domain such that each of its elements is the interpretation of a known constant of the language. We use a modification of the tableaux calculus and dual resolution to make a process which finds minimal abductive solutions within the proposed semantics. [ABSTRACT FROM AUTHOR]

The relation between deduction and abduction is explored. We observe some duality between both kinds of reasoning, what makes them neither irreducible one to the other, nor completely independent. Finally, this duality is used to define an abductive calculus and its fundamental logical properties are shown. [ABSTRACT FROM AUTHOR]

In this work we define a semantics in terms of finite structures for a first order formal language. We use semantic tableaux, with the δ′-rule instead of the δ′-rule, in order to study interpretative structures whose universe has a determined cardinality. These modified tableaux prove to be useful for investigating in the field of finite models, specifically to determine whether a sentence is finitely satisfiable, and also to define its minimal models and if it is a logical consequence of other sentences, in a sense that is specified in the paper.

Este trabajo consta de una lista de taxones determinados a nivel de familia, género y especie presentes en el Santuario de Fauna y Flora (SFF) Los Colorados en el Municipio de San Juan de Nepomuceno - Bolívar. Dichos taxones se encuentran depositados en el Herbario Nacional Colombiano de la Universidad Nacional de Colombia (COL). El área de estudio cuenta con un ecosistema de Bosque Seco Tropical. Se encuentra a 90 km al sur de Cartagena, con una extención de 1000 hectáreas, 230- 500 m y un régimen de lluvias unimodal- biestacional, concentradas éstas entre mayo y noviembre. Este trabajo se inició con la selección de ejemplares indeterminados. Luego se procedió a la determinación hasta la categoría taxonómica que fuese posible (género o especie). Con estos resultados y los encontrados en otros trabajos realizados en la localidad, se construyó una lista de especies. Así mismo, se presentan los habitos de vida dominantes y el rango altitudinal presente. En total se hallaron 46 familias, 118 géneros y 144 especies. Las familias Fabaceae (19 géneros y 26 especies), Bignoniaceae (8/15), Apocynaceae (8/9) y géneros como Senegalia (5 especies), Capparis (4), Bignonia (4), Fridericia (4) fueron los más diversos. El hábito mas abundante es de árbol (77 individuos) y las lianas con 35 individuo, que en su mayoría pertenecen a la familia Bignoniaceae. Se registraron especies bajo diferentes categorias de amenaza: dos en peligro de extinción (EN) y una como vulnerable (VU). Se realizó además un análisis climático de las precipitaciones mensuales de dos estaciones meteorológicas pluviométricas cercanas al área de estudio, a partir de registros brutos suministrados por el IDEAM. Todo para delimitar los perdiodos marcados de sequia, al ser estos un factor determinante en el arreglo florístico y la caducifolidad de la vegetacion en el BS-T. Se presenta una media mensual de 135 mm, y 1619 mm anuales. Octubre, mayo, noviembre y septiembre, con los valores más altos, consentrandose en dichos meses el 50% de todas las precipitaciones del año. Se recomienda para el SFF- Los Colorados aumentar el nivel de conocimiento florístico que hasta el momento es relativamente pobre. Para ello se sugiere revisar ejemplares depositados en colecciones del Caribe colombiano. Así mismo, es necesario implementar estrategias de conservación al encontrarse dicha zona con una alta degradación. [ABSTRACT FROM AUTHOR]
