    Razão, realismo e verdade: o que nos ensina o estudo sociognitivo da referência

    In this paper we shall examine some recent developments in the study of reference, namely those which assumes a textual, interactive, social-cognitive view of the phenomenon, and point to new contributions that Fauconnier’s Mental Spaces ‘Theory can make to this study, focusing mostly the conceptual blending process. In addition, we reflect upon the consequences of this social-cognitive view to the rationalists’ theories of mind and language, as well as to current theory of knowledge and epistemological debates

    Food security and nutrition in Mozambique: comparative study with bean species commercialised in informal markets

    In Mozambique (South-eastern Africa), Phaseolus vulgaris and Vigna spp. are important staple foods and a major source of dietary protein for local populations, particularly for people living in rural areas who lack the financial capacity to include meat in their daily dietary options. This study focuses on the potential for improving diets with locally produced nutritious legumes whilst increasing food security and income generation among smallholder farmers. Using bean species and varieties commercialised as dry legumes in the country, it sets out to characterize and compare the chemical properties of Phaseolus vulgaris and Vigna spp. among the most commercialised dry legume groups in Mozambique. The principal component analysis showed a clear separation between Phaseolus and Vigna species in terms of proximate composition, whereas protein content was quite uniform in both groups. It concludes that the introduction of improved cultivars of Phaseolus vulgaris and Vigna species maize–legume intercropping benefits yield, diets and increases household income with limited and low-cost inputs while enhancing the resilience of smallholder farmers in vulnerable production systems affected by recurrent drought and the supply of legumes to urban informal marketsinfo:eu-repo/semantics/publishedVersio

    Exploring physicochemical and cytogenomic diversity of African cowpea and common bean

    In sub-Saharan Africa, grain legumes (pulses) are essential food sources and play an important role in sustainable agriculture. Among the major pulse crops, the native cowpea (Vigna unguiculata) and introduced common bean (Phaseolus vulgaris) stand out. This paper has two main goals. First, we provide a comprehensive view of the available genetic resources of these genera in Africa, including data on germplasm collections and mapping biodiversity-rich areas. Second, we investigate patterns of physicochemical and cytogenomic variation across Africa to explore the geographical structuring of variation between native and introduced beans. Our results revealed that 73 Vigna and 5 Phaseolus species occur in tropical regions of Africa, with 8 countries accounting for more than 20 native species. Conversely, germplasm collections are poorly represented when compared to the worldwide collections. Regarding the nuclear DNA content, on average, V. unguiculata presents significantly higher values than P. vulgaris. Also, V. unguiculata is enriched in B, Mg, S, and Zn, while P. vulgaris has more Fe, Ca, and Cu. Overall, our study suggests that the physicochemical and cytogenomic diversity of native Vigna species is higher than previously thought, representing valuable food resources to reduce food insecurity and hunger, particularly of people living in African developing countriesinfo:eu-repo/semantics/publishedVersio

    Lantern in the bow: on the recent tradition in the study of linguistics

    No full text
    Review of the recent history of linguistics from the viewpoint of its current developments: the ripening of the young field of cognitive sciences (specially, technologies of information and neurosciences) leads to substantive methodological revisions in linguistic analysis, which tends to become more interdisciplinary, more collegial and more committed to empirical verification by theoretical-independent classes of evidence
