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
FrameNet Brasil: A work in progress
Presentation of the project of lexicographical annotation FrameNet Brasil, which includes its theoretical support (frame semantics), its connection to the project FrameNet, in Berkeley, California, its present stage of implementation, and the issues that this kind of semantic analysis suggests about meaning. Key words: lexical semantics, frames, lexicon, lexicography.<br /
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
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
