Composição fotojornalística e história: função testemunhal como ato performativo e interação de linguagens

Assuming that testimony in photojournalism must be understood as a historical and performative act, the aim of this article is to discuss how the testimonial function of journalistic photography was constantly re-signified in Brazilian news magazines during the twentieth century. This redefinition has a relation with the different ways in which testimonial function was hinged to news report (in its broadest elements) and how this imperative appeared on its discursive form in writing narrative. As trustee of a narrative intended to be realistic, photojournalism articulates, from techniques and codes of narration, a series of referential and informational strategies. These strategies, however, have changed over time, based on different modes of narration by image and its accreditation in reality.

Ocorrências e usos do Tucumã (astrocaryum vulgare mart) em comunidades ribeirinhas, quilombolas e de agricultores tradicionais no município de Irituia, Pará

The aim of the study is to demonstrate the occurrence and usage of the Tucumã (Astrocaryum vulgare Mart.) in rural areas of the Municipality of Irituia, in the State of Pará (Brazil), since the use of the palm part of the traditional culture of communities of farmers, riparian and quilombola, used in curing diseases in human and domestic animals, building shelters, obtaining fibers, production of tools and crafts, hunting and fishing. In addition to the uses reported by the population, tucumã has potential for the production of oil and biodiesel. In this sense, the Federal University of Pará – UFPA, in a partnership with the Irituia’s Municipal Government, is studying the implementation of an oleaginous processing plant in the municipality, among them, and includes the Tucumã as a potential source. Such proposal stipulates the production in the agroforestry system, as an alternative to the slash and burn agriculture in the region, reconciling environmental conservation with territorial rural development. Considering the results obtained in the field, it has been found an average of 9.4 stumps per hectare, each stump having 7.7 stipes and 4.7 racemes with up to 146 fruits. If all the Tucumã’s stumps were kept until they reached their average productivity capacity, it is estimated that the fruit production in the rural area of the municipality would be around 132.060 tons, which could produce up to 12.665,4 tons/year of pulp oil and 4.768,4 tons/year of nut oil, confirming the supply of raw material to move this productive chain.
