Thinking machines and future education: the Non-Axiomatic Reasoning System (NARS) program |
López Astorga, Miguel |
|
Abstract: |
In this paper, we study the Pei Wang’s approach and his new non-axiomatic logic. Therefore, we analize the NARS program, based on such non-axiomatic logic and that, according to its author, imitates human reasoning, aiming to describe its reach, limitations and possibilities for use in education. The proposal is also reviewed from different theoretical approaches of contemporary philosophy of science and cognitive science. Finally, the difficulties faced by any project aimed to make a human reasoning simulation machine, able to accomplish scientific discoveries and able to teach are stated.

(Inter)Disciplinary Intervention: scope and limits of the technical teams for pedagogical support |
Bertoldi, Sandra M.; Enrico, Liliana N. |
|
Abstract: |
The concept of interdisciplinarity has been subject of debates and controversial opinions as regards to it’s theoretical development and there is no agreement about the extension and limits of the so-called interdisciplinary practices. Interdisciplinary teams aimed to give assistance in case of pedagogical problems arising in primary and secondary schools exist in the educational system of the Province of Rio Negro (Argentina) since 1986. However, there is not a unique way to carry out those interventions. In this paper, different modalities of relationship between prescriptive regulations and the teams’ interventions in secondary schools are discussed based on some results of our research, showing strictly the scope and limits of the interdisciplinarity from the professional technicians’ point of view.

Marxism and university in the journal Mikael (1973-1984) |
Rodríguez, Laura Graciela |
|
Abstract: |
The journal Mikael was part of a wider network of publications of the preconciliar Catholic nationalism, whose editors supported strongly the last military coup in Argentina. It was created in 1973 by Monsignor Adolfo S. Tortolo, rector of the theological seminary of Paraná, Entre Ríos Province. In this paper we will analyze the articles about the university published in Mikael, the public careers of their authors and the networks of relationships established among themselves and with other publications at that time.

Antibacterial activity of medicinal plants in the flora of Entre Ríos (Argentina) |
Vivot, Eduardo; Sánchez, Cecilia; Cacik, Francisco; Sequin, Christian J. |
|
Abstract: |
Traditionally employed medicinal plants are a resource for new drugs needed to address microbiological conditions produced by the acquired resistance of microorganisms and the increased number of immunosuppressed people. The background of ethnobotanical flora of Entre Ríos includes numerous species used to cure infections. For the present study there were selected: Acacia bonariensis; Baccharis articulata; Blepharocalyx salicifolius; Castela tweedii; Eichhornia azurea; Eichhornia crassipes; Erythrina crista-galli; Gaillardia megapotamica var. scabiosoides; Hydrocotyle bonariensis; Ludwigia peploides; Pistia stratiotes; Phytolacca dioica; Porlieria microphylla; Senna scabriuscula; Schinus fasciculatus y Typha. We evaluated antibacterial activity of methanolic, hydroalcoholic and aqueous plant extracts by the diffusion method on solid medium using standarized bacterial strains to verify the sensitivity to these extracts. The results show antibacterial activity in vitro of numerous extracts of most species, and of several ones against a clinical strain of Streptococcus aureus methicillin resistant.

PROT 12 FCA: a new no transgenic soybean cultivar with high protein |
Fresoli, Diana M.*; Beret, Patricia N.*; Hirschfeld Yanina** |
|
Abstract: |
In soybean, the average percentage of proteins in grain in the last few decades has been 38.80 %. The general aim of the work was to develop lines of soybean from exotic germoplasm with protein content higher than the national average and with high yields. Genetic improvement began with the introduction of genotypes followed by hybridization and subsequent selection. The process resulted in the registration at the National Register of Cultivars Property of the new cultivar PROT12FCA, which presents a content in protein and oil of 42.46 % and 20.42 % respectively, surpassing the witnesses performance on a 5 %. It is resistant to stem canker and to the race 1 of Phytophthora sojae.

Relative Tetrapod Vulnerability in Arroyo Zabala Reserve (Buenos Aires, Argentina) |
Leber, Virginia; Kristensen, María Julia |
|
Abstract: |
Tetrapods have characteristics of vulnerability that make them adequate as a focus of attention when management priorities need to be established in protected areas. The aim was to determine the relative vulnerability of amphibians, reptiles, and mammals of verified or potential occurrence in one Multiple Use Nature Reserve in Buenos Aires Province (Argentina), in order to contribute to its management plan. We applied a vulnerability index (sumin) on the lists of species based on the literature available and interviews. Eight species were categorized as of highest priority of conservation: 11.11 % of amphibians, 15.79 % of reptiles, and 15.39 % of mammals. Eighteen other species were categorized as needing special attention: 33.33 % of amphibians, 31.58 % of reptilians and 34.62 % of mammals.
