- Seed coating with arbuscular mycorrhizal fungi as an ecotechnologicalapproach for sustainable agricultural production of common wheat (Triticum aestivumL.)Publication . Oliveira, Rui S.; Rocha, Inês; Ma, Ying; Vosátka, Miroslav; Freitas, HelenaThe exploitation of arbuscular mycorrhizal (AM) fungi has become of great interest in agriculture due to their potential roles in reducing the need for agrochemicals, while improving plant growth and nutrition. Nevertheless, the application of AM fungi by dispersing inocula in granular form to open agricultural fields is not feasible because nontargeted spreading of inocula over large surface areas results in high cost per plant. Seed coating has the potential to significantly reduce the amount of inoculum needed, resulting in cost reduction and increased efficiency. The aim of this study was to assess whether seed coating with AM fungal inoculum is a feasible delivery system for production of common wheat (Triticum aestivum L.). Wheat seeds were coated with inoculum of Rhizophagus irregularis BEG140 and grown under different fertilization conditions: (1) none, (2) partial, or (3) complete. Data indicated that mycorrhizal inoculation via seed coating significantly increased the dry weight of shoot and seed spikes of wheat associated with reduced fertilization. Assessment of nutritional status of wheat showed that plants inoculated with R. irregularis via seed coating displayed enhanced stem concentrations of potassium (K), sulfur (S), and zinc (Zn). There were no significant differences in root colonization between plants conventionally inoculated with R. irregularis in soil and those inoculated via seed coating. Seed coating with AM fungi may be as effective as conventional soil inoculation and may contribute to reduce the utilization of chemical fertilizers. The application of AM via seed coating is proposed as an ecotechnological approach for sustainable agricultural wheat production.

- Criatividade e cognição na emergência da personagemPublication . Castro, Maria GuilherminaA personagem tem sido tratada de modo muito diverso nas publicações relativas a diferentes campos artísticos, como o Teatro, o Cinema, a Literatura ou a Animação, sendo francamente negligenciada em algumas delas. Não obstante, é uma componente fundamental no ensino-aprendizagem da narrativa naquelas e noutras formas artísticas. Dada a importância da personagem em diversas áreas, iniciou-se um estudo que procura compreender, interdisciplinarmente, os processos cognitivos usados na busca da sua ideia, com intuito último de elaborar exercícios que constituam ferramentas criativas para artistas e aprendizes. Para tal, na primeira fase, que aqui se descreve, desenvolveu-se um estudo empírico exploratório, no qual se realizaram 20 entrevistas orais a artistas (argumentistas, realizadores, animadores, atores, escritores…), focadas no modo como criam personagens. Uma abordagem indutiva de análise de conteúdo conduziu à identificação de processos criativos suscetíveis de serem interpretados à luz da Teoria das Inteligências Múltiplas de Gardner (1983, 1999). O autor considera que, além das formas de inteligência classicamente entendidas enquanto tal (verbal e lógico-matemática), outras formas preferenciais de conhecer e adaptar-se à realidade fazem jus a esta designação: visual-espacial, musical, corporal-cinestésica, intrapessoal, interpessoal e naturalista. Qual a relação entre inteligência e criatividade? Gardner (1999) acrescenta que se, por um lado, os caminhos cognitivos tendenciais do indivíduo se associam ao domínio em que se manifesta criativo, por outro, na genialidade, combinam-se com uma outra forma de inteligência, inabitual para esse domínio. O filme La Leggenda del Pianista Sull'oceano, de Giuseppe Tornatore (1998), evidencia-o magistralmente.
- Scarcity, economics and morality: the contribution of the late Iberian scholasticsPublication . Alves, André Azevedo; Moreira, PedroWhile for many centuries Augustine and Christianity in general emphasized the provisional and hazardous character of earthly life, the Iberian scholastics of the Salamanca School were central actors in the development of a deeper, more positive, and arguably more affirmative outlook on worldly political and economic matters. In this paper, we attempt to show this transition through the evolution of the concept of ‘scarcity.’ Indeed, ‘scarcity’ is a central premise of positive modern economics but for many centuries this concept was used to high-light normative conclusions in the writings of medieval theologians. The Iberian scholastics were instrumental in a shift from normative to positive, trying to find better ways to cope with the material world and improve our earthly lives within an integrated philosophical and theological perspective. We will illustrate this through the study of Domingo de Soto, one of the Iberian scholastics.
