Modelling group decision simulation through argumentation

Group decision making plays an important role in today’s organisations. The impact of decision making is so high and complex, that rarely the decision making process is made individually. In Group Decision Argumentation, there is a set of participants, with different profiles and expertise levels, that exchange ideas or engage in a process of argumentation and counter-argumentation, negotiate, cooperate, collaborate or even discuss techniques and/or methodologies for problem solving. In this paper, it is proposed a Multi-Agent simulator for the behaviour representation of group members in a decision making process. Agents behave depending on rational and emotional intelligence and use persuasive argumentation to convince and make alternative choices.

Lettuce (Lactuca sativa L.) leaf-proteome profiles after exposure to cylindrospermopsin and a microcystin-LR/cylindrospermopsin mixture: A concentration-dependent response

The intensification of agricultural productivity is an important challenge worldwide. However, environmental stressors can provide challenges to this intensification. The progressive occurrence of the cyanotoxins cylindrospermopsin (CYN) and microcystin-LR (MC-LR) as a potential consequence of eutrophication and climate change is of increasing concern in the agricultural sector because it has been reported that these cyanotoxins exert harmful effects in crop plants. A proteomic-based approach has been shown to be a suitable tool for the detection and identification of the primary responses of organisms exposed to cyanotoxins. The aim of this study was to compare the leaf-proteome profiles of lettuce plants exposed to environmentally relevant concentrations of CYN and a MC-LR/CYN mixture. Lettuce plants were exposed to 1, 10, and 100 lg/l CYN and a MC-LR/CYN mixture for five days. The proteins of lettuce leaves were separated by twodimensional electrophoresis (2-DE), and those that were differentially abundant were then identified by matrix-assisted laser desorption/ionization time of flight-mass spectrometry (MALDI-TOF/TOF MS). The biological functions of the proteins that were most represented in both experiments were photosynthesis and carbon metabolism and stress/defense response. Proteins involved in protein synthesis and signal transduction were also highly observed in the MC-LR/CYN experiment. Although distinct protein abundance patterns were observed in both experiments, the effects appear to be concentration-dependent, and the effects of the mixture were clearly stronger than those of CYN alone. The obtained results highlight the putative tolerance of lettuce to CYN at concentrations up to 100 lg/l. Furthermore, the combination of CYN with MC-LR at low concentrations (1 lg/l) stimulated a significant increase in the fresh weight (fr. wt) of lettuce leaves and at the proteomic level resulted in the increase in abundance of a high number of proteins. In contrast, many proteins exhibited a decrease in abundance or were absent in the gels of the simultaneous exposure to 10 and 100 lg/l MC-LR/CYN. In the latter, also a significant decrease in the fr. wt of lettuce leaves was obtained. These findings provide important insights into the molecular mechanisms of the lettuce response to CYN and MC-LR/CYN and may contribute to the identification of potential protein markers of exposure and proteins that may confer tolerance to CYN and MC-LR/CYN. Furthermore, because lettuce is an important crop worldwide, this study may improve our understanding of the potential impact of these cyanotoxins on its quality traits (e.g., presence of allergenic proteins).

Características y desarrollo del acogimiento familiar en dos países con fuerte tradición de acogimiento residencial: España y Portugal

Los procesos de acogimiento familiar que se producen en cada país dependen de factores históricos y culturales que dan lugar a grandes diferencias internacionales. A pesar de que las comparativas internacionales ofrecen un medio de intercambio de experiencias, lo que permite el aprendizaje mutuo y la transferencia de buenas prácticas, a menudo encontramos enormes barreras para su realización debido, entre otros factores, al limitado acceso a los datos sobre la práctica de la protección infantil. Frente a estas limitaciones, este artículo ofrece una investigación comparativa realizada en España y Portugal, cuyo objetivo ha sido la evaluación del acogimiento familiar en dos países donde la investigación en el ámbito de la protección infantil há sido tradicionalmente desatendida. Sobre una muestra de 357 casos en España y 289 en Portugal, se realizó un estudio del perfil de características de los niños acogidos, las familias de origen y los acogedores, así como de los procesos de acogida en ambos países. La comparativa reveló importantes diferencias relacionadas con la mayor edad al inicio del acogimiento de los niños en España; el perfil de los acogedores, con edades más avanzadas, un bajo nivel educativo y llevando a cabo acogidas de más de un niño simultaneamente en Portugal. El estudio comparado nos ha permitido identificar áreas que requieren mayor atención en ambos países, como la renovación generacional del banco de acogedores en Portugal o la necesidad de acelerar los procesos de toma de decisiones para la entrada en acogimiento familiar en España. Se pretende que este artículo sirva de aliento para la recogida de datos y comparación con otros países iberoamericanos.

História, religião e literatura. caminhos que se cruzam no feminino

Soror Antónia Baptista, religiosa professa no Convento da Esperança de Vila Viçosa, redigiu o Livro da Fundação do santo Convento de nossa Senhora da esperança de Villa viçoza e de algũas plantas que em elle se criarão pera o ceo dignas de memoria, concluído em 1657. Trata-se de um exemplar único, autógrafo, que permaneceu manuscrito até hoje. A faceta de cronista da autora coabita com a de poetisa, almejando uma intencionalidade didática, de doutrinação, ao propor modelos de santidade de religiosas que viveram no convento da Esperança de Vila Viçosa, aspirando à plenitude da perfeição religiosa. Ao perpetuar as figuras que traz à memória, Soror Antónia imortaliza, simultaneamente, a história do convento, cumprindo deste modo um propósito identitário que respeita a comunidade religiosa do mesmo convento. A análise que se impõe propicia a reconstituição de um retrato epocal, com base na compreensão da história local e regional, fornecida pelas frequentes alusões aos hábitos de vida comunitária, práticas devocionais e pelas relações do convento com o exterior. A filiação do texto de Soror Antónia Baptista a obras coevas permite inseri-lo no filão da escrita conventual feminina direcionada para as obras de "fundação".
