Fábrica de Coringas: estratégias avaliativas na construção de sentido no texto jornalístico
This work has as theoretical framework the Systemic-Functional Linguistics (HALLIDAY, 1985, 1989, 2014; FUZER; CABRAL, 2014), which sees language as a sociosemiotic system related to society; as well as (WHITE, 2004; MARTIN; WHITE, 2005) to refer to the Evaluation System and (ROSE; MARTIN, 2012) as a contribution to genre. Therefore, the main objective of this article is to verify how the Appraisal System (WHITE, 2004; MARTIN; WHITE, 2005) contributes to the construction of meanings in the opinion text entitled “Fábrica de Coringas” (SCHNEIDER, 2019). Thus, we aim at presenting, through the analysis of the author’s semantic discoursive choices, made by analogy with the stereotype of the character Joker, the government’s disregard for social issues that happened in Brazil. The methodology adopted for the analysis of the corpus is organized in the following steps: 1) segmentation of the text in stages, according to the guidelines of Rose and Martin (2012); 2) identification of the author’s evaluations with respect to the people and their rulers; 3) identification and classification of the occurrences of the Evaluative system based on the categories proposed by Martin and White (2005); 4) description of the realization of meanings in the text based on the use of resources available in semantics of the discourse; 5) verification of how the author makes linguistic choices in order to be aligned with the reader. The results revealed the predominance of appreciation resources by negative composition and valuation to configure the current social, economic and political situation in Brazil. Such values are intensified by the force-intensification grading subsystem.Este trabalho tem como fundamentação teórica a Linguística Sistêmico- Funcional (HALLIDAY, 1985; 1989; 2014; FUZER; CABRAL, 2014), que vê a linguagem como sistema sociossemiótico relacionado com a sociedade, bem como o Sistema de Avaliatividade (WHITE, 2004; MARTIN; WHITE, 2005) e o estudo de gêneros (ROSE; MARTIN, 2012). Assim, o objetivo principal deste artigo é verificar como o Sistema de Avaliatividade (WHITE, 2004; MARTIN; WHITE, 2005) contribui para a construção de significados no texto de opinião intitulado “Fábrica de Coringas” (SCHNEIDER, 2019). Dessa forma, buscamos apresentar, por meio da análise das escolhas semântico-discursivas do autor, realizadas pela analogia com o estereótipo do personagem Coringa, o descaso do governo com as questões sociais enfrentadas hoje no Brasil. A metodologia adotada para a análise do corpus está organizada nos seguintes passos: 1) segmentação do texto em etapas, conforme as orientações de Rose e Martin (2012); 2) identificação das avaliações autorais referentes ao povo e aos governantes; 3) identificação e classificação das ocorrências do sistema de Avaliatividade com base nas categorias propostas por Martin e White (2005); 4) descrição da realização dos significados no texto com base no uso de recursos disponíveis na semântica do discurso; 5) verificação de como o autor realiza as escolhas linguísticas com o intuito de buscar o alinhamento com o leitor. Os resultados revelaram a predominância de recursos de apreciação por composição e valoração negativos para configurar a situação social, econômica e política atual do Brasil. Tais valores são intensificados pelo subsistema de gradação do tipo força intensificação
Osteossarcoma secundário à doença de Paget: relato de caso
É uma doença óssea localizada, monostótica ou poliostótica, com aumento da remodelação óssea, levando à anormalidade da sua arquitetura. A excessiva reabsorção osteoclástica e o aumento da atividade osteoblástica levam à substituição do osso normal por osso desorganizado e de estrutura enfraquecida, propensa a deformidades
Combining ecological, social and technical criteria to select species for forest restoration
Question How to evaluate and integrate relevant ecological, social and technical criteria to select species to be introduced in restoration projects of highly diverse ecosystems such as tropical riparian forests. Location Riparian forest, Marqués de Comillas municipality, southeast Mexico (16°54′N, 92°05′W). Methods We proposed a 'species selection index' ( SSI) using five independent criteria related to ecological, social and technical information. SSI targeted species that (1) are important in the reference forest; (2) are less likely to establish following disturbance; (3) are not specific to a particular habitat; (4) are socially accepted; and (5) their propagation requires a reasonable time and financial investment. SSI may range between zero and 50, with higher values meaning higher potential for restoration purposes. Results Out of a local pool of 97 species, we identified 30 target tree species that together represented >60% of total importance value index in the reference riparian forests. SSI averaged 28.3 ± 1.0 over the studied species, suggesting that species with high values are not frequent. For 20 species, reintroduction by means of active forest restoration was deemed necessary. Species that established through natural regeneration, following secondary regrowth, had lower social value among local farmers. Nearly half of the identified species showed technical constraints for easy propagation and seeding. Conclusions The proposed procedure is useful for selecting species to initiate forest restoration projects and of other woody ecosystems that harbour high biodiversity, and is suitable for several stakeholders interested in restoration
Proteome profiling of early seed development in Cunninghamia lanceolata (Lamb.) Hook
Knowledge of the proteome of the early gymnosperm embryo could provide important information for optimizing plant cloning procedures and for establishing platforms for research into plant development/regulation and in vitro transgenic studies. Compared with angiosperms, it is more difficult to induce somatic embryogenesis in gymnosperms; success in this endeavour could be increased, however, if proteomic information was available on the complex, dynamic, and multistage processes of gymnosperm embryogenesis in vivo. A proteomic analysis of Chinese fir seeds in six developmental stages was carried out during early embryogenesis. Proteins were extracted from seeds dissected from immature cones and separated by two-dimensional difference gel electrophoresis. Analysis with DeCyder 6.5 software revealed 136 spots that differed in kinetics of appearance. Analysis by liquid chromatography coupled to tandem mass spectrometry and MALDI-TOF mass spectrometry identified proteins represented by 71 of the spots. Functional annotation of these seed proteins revealed their involvement in programmed cell death and chromatin modification, indicating that the proteins may play a central role in determining the number of zygotic embryos generated and controlling embryo patterning and shape remodelling. The analysis also revealed other proteins involved in carbon metabolism, methionine metabolism, energy production, protein storage, synthesis and stabilization, disease/defence, the cytoskeleton, and embryo development. The comprehensive protein expression profiles generated by our study provide new insights into the complex developmental processes in the seeds of the Chinese fir
Assessment of impacts on ecosystem services provided by geodiversity in highly urbanised areas: a case study of the Taubaté Basin, Brazil
This work presents a method to identify, to evaluate and to quantify the losses of the offer of ecosystem services provided by geodiversity, using as a case study the Taubaté Basin region, a highly urbanized portion of southeastern São Paulo State, Brazil. Our method considers not only the qualitative analysis of the abiotic as- pects, but also the historical and cultural context, in which the geodiversity elements are crucial for local economy development. The method is based on: i) Qualitative evaluation and definition of six Essential Geodiversity Variables (EGVs), used as the basis for the identification of 53 ecosystem services distributed into four functions: regulating, supporting, provisioning, and cultural; ii) Definition of land use categories based on two land use maps elaborated in order to compare the transformation occurred in the region between 1986 and 2016; iii) Quantification and evaluation of the impacts on the offer of ecosystem services caused by land use transformations occurred in region in a 30–year gap. The results showed that anthropogenic action is the main factor that alter the availability of local services, with emphasis on the supply of water, soils and mineral resources, and its potentially influence on the quality of life of certain species. We reinforce the view that public policies on land management and planning should consider the ecosystem assessment, as it provides evidence to propose actions to mitigate impacts and for environmental compensation, favoring the sustainable use of re- sources by society.The authors would like to thank CAPES for the Academic Mobility

The ocean sampling day consortium
Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world’s oceans. It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a single day. This will be achievable only through the coordinated efforts of an Ocean Sampling Day Consortium, supportive partnerships and networks between sites. This commentary outlines the establishment, function and aims of the Consortium and describes our vision for a sustainable study of marine microbial communities and their embedded functional traits
Evaluation of neuromotor development by means of the Harris Infant Neuromotor Test
Objective: To investigate the neuromotor development of at-risk children between three and 12 months of life, administering the Brazilian version of the Harris Infant Neuromotor Test (HINT).Method: A longitudinal study, with 78 children and 76 parents/guardians discharged from a neonatal intensive care unit in Fortaleza-CE/Brazil. Two instruments were administered: HINT and a socioeconomic questionnaire, between July/2009 to August/2010. Data from 55 preterm and 23 term children were analyzed. Results: The final mean scores ranged from 14.6 to 25.2 and from 11.2 to 24.7, for preterm and term, respectively, showing that 91% of children demonstrated good neuromotor performance; seven premature infants showed alterations which led to the referral of three children to a specialized clinic for examination and diagnostics.Conclusion: The test allowed nurses to assess infant development, identify deviations early, and plan interventions
Urban environmental quality and wellbeing in the context of incomplete urbanization in Brazil: integrating directly experienced ecosystem services into planning
The benefits of urban greenspace to residents are increasingly recognized as important to planning for sustainable and healthy cities. However, the way that people interact with and benefit from urban greenspace is context dependent and conditioned by a range of social and material factors. This paper applies and expands the ecosystems services based approach to understanding urban environmental quality and the way in which greenspace is appropriated by residents in the context of incomplete urbanization in three peri-urban target areas in Brazil. We develop and employ the notion of indirect (scientifically detected) and directly experienced ecosystems services, and undertake a science based ecosystem services assessment and a qualitative analysis of interviews, walking narratives and images captured with a smartphone application to understand what functions urban greenspace serves in the daily life of the studied neighborhoods. Findings demonstrate how elements of urban greenspace and what can be termed ecosystem services serve both material and signifying functions and produce subjective and collective benefits and dis-benefits that hinge on aspects of livability such as quality of urban service delivery, housing status and perceptions of crime and neighborhood character. We identify factors that enable, hinder and motivate both active material and interpretative interactions with urban greenspace. The findings suggest that the relationship between ecosystem service provision and wellbeing is better understood as reciprocal rather than one way. Although at the neighborhood scale, fear of crime and poor access to urban services can hinder positive engagements with urban greenspace and experienced benefits form ES, urban squares and fringe vegetation is also being appropriated to address experienced disadvantages. Presently however these local interactions and ecosystem service benefits are overlooked in formal planning and conservation efforts and are increasingly compromised by growing population density and environmental degradation. We make recommendations for a nuanced assessment of the material and interpretative human-nature interactions and associated ecosystem services in an urban context, and discuss the potential for planning initiatives that could be employed to articulate and nurture these important interactions in our target areas
