Para pensar comunicação, cultura e subjetividade: uma perspectiva de análise

O presente texto procura fazer uma síntese da perspectiva que defendemos para a análise das relações entre comunicação, cultura e subjetividade. Trata-se, nos três âmbitos, de evitar o que nomeamos de paradigma epocalista, em favor de abordagens localizadas e atentas às diferenças. Nossa perspectiva envolve, em primeiro lugar, evitar uma visão classificatória das subjetividades. Além disso, evita-se a redução da história das culturas a uma sucessão linear de épocas. Finalmente, evita-se, do mesmo modo, tanto o determinismo tecnológico quanto a ideia de um usuário onipotente, o que implica considerar tanto as agências das tecnologias quanto as ações dos usuários tomados individual ou coletivamente.This article summarizes the perspective we favor for the analysis of the relationships between communication, culture and subjectivity. In all three domains, it is about avoiding what we call the epochalist paradigm, in favor of localized approaches attentive to differences. Our perspective involves, first of all, avoiding a classificatory view of subjectivities. In addition, reduction of cultural history to a linear succession of epochs is avoided. Finally, both technological determinism and the idea of an omnipotent user are avoided as well, which implies considering both technology agencies and user actions, on an individual or collective basis

Poeira continental soprada pelo vento como combustível para paleoprodutividade ao longo do sudoeste do Oceano Atlântico durante o último período glacial

Glaciogenic dust has a strong relationship with global climate and ocean biogeochemical processes especially during glacial periods, being a major source of nutrients, mainly iron, that increase marine productivity. Different studies have attributed higher marine paleoproductivity along the southwestern Atlantic during the last glacial period to fluvial inputs and upwelling, but the possible influence of continental dust on that process is still unknown. This paper presents evidence suggesting that eolian-sourced glaciogenic dust favored higher ocean productivity during the last glacial, recorded in three sediment cores obtained on the lower continental slope off southern Brazil (~29°-30°S, ~47°W) at water depths between 1,514 and 2,091 m. The sampled sediments are silt-dominated terrigenous siliciclastics, but higher proportions of sand-sized biogenic carbonate (mostly foraminifer tests) at intervals corresponding to the stadials MIS 4 and 2 and parts of the interstadial MIS 3 point to intervals of increased productivity, correlated with pulses of higher deflation of dust from southern South America as recorded in the EPICA Dome C ice core in Antarctica. It is proposed that glacial climate-driven increased eolian processes transported iron-bearing dust produced by the expanded Patagonian ice sheet up to the southwestern Atlantic, fueling higher phytoplankton productivity and thus favoring the proliferation of planktonic and benthic foraminifera recorded in the cores. Eventual anthropogenically-driven reduction of tropical-sourced summer rainfall reaching southern South America, driven by equatorial ocean warming and deforestation in the Amazon region, may increase dust deflation and thus affect ocean productivity along the southwestern Atlantic in the future.A poeira glaciogênica tem forte relação com o clima global e os processos biogeoquímicos oceânicos, principalmente durante os períodos glaciais, sendo uma importante fonte de nutrientes, como o ferro, que aumentam a produtividade marinha. Diferentes estudos tenham atribuído a maior paleoprodutividade marinha ao longo do Atlântico sudoeste durante o último período glacial a aportes fluviais e ressurgência, mas a possível influência da poeira continental nesse processo ainda é desconhecida. Este artigo apresenta evidências sugerindo que a poeira glaciogênica de origem eólica favoreceu maior produtividade oceânica durante a última glaciação, registrada em três testemunhos sedimentares obtidos no talude continental inferior no sul do Brasil (~29°-30°S, ~47°W) em profundidades da lâmina d'água entre 1.514 e 2.091 m. Os sedimentos amostrados são siliciclásticos terrígenos dominados por silte, mas maiores proporções de carbonato biogênico de tamanho areia (principalmente testes de foraminíferos) em intervalos correspondentes aos estadiais MIS 4 e 2 e partes do interestadial MIS 3 indicam intervalos de maior produtividade, correlacionados com pulsos de maior deflação de poeira do sul da América do Sul, conforme registrado no testemunho de gelo antártico obtido no EPICA Domo C. Propõe-se que os processos eólicos intensificados devido ao clima glacial transportaram para o Atlântico sudoeste poeira contendo ferro produzida pela expansão do manto de gelo da Patagônia, alimentando uma maior produtividade do fitoplâncton eassim favorecendo a proliferação de foraminíferos planctônicos e bentônicos registrados nos testemunhos. A eventual redução antrópica das chuvas de verão de origem tropical que atingem o sul da América do Sul, impulsionada pelo aquecimento do oceano equatorial e pelo desmatamento na região amazônica, pode aumentar a deflação de poeira, assim afetar a produtividade do oceano ao longo do Atlântico sudoeste no futuro

The role of Knowledge Media in Network Education

An efficient model of education is always closely related to a vision of society. The conception of network society places as a priority a network education model. The general objective of this article is to establish the foundations of network education and its relationship with the knowledge media. The methodology used in this research will be qualitative, descriptive with theoretical approach. The first section will establish the foundations of network education, based on the vision of network society, and its difference from distance education models based on the use of information and communication technologies. In the second section the concepts of “knowledge media” will be analysed and discussed. The third section will address the relationship between network education and the knowledge media. The fourth section will establish the possibilities and limits of network education within the scope of knowledge communication. The result of the theoretical reflection points to a network education model in the digital age based on the network society, within the scope of knowledge communication, aiming to establish the knowledge dialogue through knowledge media

Impact of programs on competency, career, and income on management graduates

Purpose – This paper aims to evaluate the impact of Federal University of Bahia’s Business Administration graduate programs on graduates’ competency, career and income development. Design/methodology/approach – It is a descriptive study, for which a survey was applied and the data were analyzed using quantitative techniques (descriptive analysis, factorial analysis, t-test, Mann–Whitney test and regression analysis). Data collection was conducted through an electronic questionnaire sent to the graduates in the period between 1998 and 2012. Findings – The results show that in general, the research participants perceive competency, career and income development after the course. At the same time, a comparison between the graduates of academic and professional axes (courses) was carried out, and in general, there is a certain similarity between perceptions. Originality/value – This research contributes to the theoretical field on evaluation of graduates, both from a methodological point of view, because of conducted statistical analysis that is complementary to other methods used, and from a practical point of view, as it offers redesign and improvement elements to the program’s curricula and teaching-learning methodologies so that it can maximize competency development, career and income of graduates

Designing for the pandemic: individual and collective safety devices

The rapid spread of COVID-19 has generated a demand for health-related safety equipment. The development of these emergency products raises several questions, in particular the possible lack of concern for health, satisfaction, and safety of users in addition to the immediate safety against the COVID-19. Considering these issues, the objectives of this work are to categorize, identify trends, and propose strategic approaches to the development and alteration of individual and collective safety solutions for facing the pandemic. For that, we conducted a review and categorization of industrial design products developed during the pandemic using the database Behance. We found 171 developed products. Of these, we classified 99 as individual safety solutions, with the majority being masks and face shields, 59 as being collective safety solutions like disinfection booths, physical transparent separators, and sanitary dispensers. And 13 were solutions geared to hospital use such as hospital furniture, testing solutions, and medical safety procedures. From the analysis of these products, we noted four major themes: protection from the infection, isolation, and physical barriers for enabling safe interaction, disinfection, and testing that can be used as a strategic guideline for the development of new solutions for this context

O texto, o livro, o sentido e o leitor

The issue of meaning production in written communication is discussed through the analysis of three different material presentations of the Gospels: a handwritten codex, a printed book and a tablet. Starting with a distinction between “text" and "book", the paper states that material supports are important in the construction of meaning without, however, relegating to the background, as unimportant, questions of uses, appropriations by readers and, of course, the text. A minimal cartography designed to map the production of meaning in reading is proposed, involving the text, the material aspects of its presentation, the individual and social dimension of the readers.Discute-se a questão da produção de sentido na comunicação letrada através da abordagem de três apresentações diferentes dos Evangelhos: uma apresentação manuscrita, uma impressa e uma digital. Partindo de uma distinção entre “texto” e “livro”, defende-se a ideia de que os suportes materiais são importantes na construção dos sentidos sem contudo relegar ao segundo plano, como pouco importantes, as questões dos usos, das apropriações dos leitores e, obviamente, do texto. É desenhada uma proposta de cartografia mínima para o mapeamento da produção de sentido, envolvendo o texto, os aspectos materiais de sua apresentação, a dimensão individual e a social dos leitores

Enriching entity grids and graphs with discourse relations: the impact in local coherence evaluation

This paper describes how discursive knowledge, given by the discursive theories RST (Rhetorical Structure Theory) and CST (Crossdocument Structure Theory), may improve the automatic evaluation of local coherence in multi-document summaries. Two of the main coherence models from literature were incremented with discursive information and obtained 91.3% of accuracy, with a gain of 53% in relation to the original results.FAPES
