As vagabundagens de Dioniso apresentadas na tribo de skatistas streeters

O estudo discute, na perspectiva do imaginário social, o conceito de tribo em Maffesoli (2000), sentidos de aventura e risco entre jovens skatistas streeters que o praticam como lazer. Captadas durante o estudo do giro pela cidade dessa tribo que parece querer se enquadrar fora do formalismo das práticas urbanas, adotando estilos próprios, singulares: de praticar os seus esportes e o sentido afetual desses ajuntamentos. A aventura e o risco assumem sentido de vertigem manifestadas na sensação corporal de medo/prazer; o lúdico aparece na exploração do espaço da cidade, criação e utilização de obstáculos; o sentido de autocontrole aparece aglutinado tanto ao empreendedorismo quanto ao sentido de expansão, o que pode ser indício de domínio do exercício dessa atividade que se realiza num meio urbano, cujas informações estão fora de seu controle, à mercê das variações do ambiente; a estrutura de sensibilidade do herói, guerreiro solar, vigilante constante, dominada pelo controle do espaço e da visão (Durand, 1989). O vôo, o pássaro e a liberdade surgiram como encadeamento semântico que deu pistas da simbologia que orienta as ações desses skatistas. Os símbolos reforçam a idéia da potência que move as ações dos praticantes gerando a força proxêmica e ecológica presente nas tribos. O mito pregnante de Dioniso vem dar suporte ao impulso lúdico, transgressor desnorteante e anônimo que aparece manifestado na trajetória desses jovens skatistas streeters pelas ruas da cidade. Eles se apresentam como novos arquitetos urbanos, amantes da cidade que os agasalha e que, ao mesmo tempo, desconfia de suas manobras

Nursing workload in a hematology/oncology inpatient unit

RESUMEN: Objetivo: Identificar los factores relacionados con la carga de trabajo de enfermería generada por pacientes onco-hematológicos hospitalizados. Método: Cohorte prospectivo realizado con 151 pacientes ingresados en unidad de Onco-Hematología de un hospital universitario, en el Estado de São Paulo, Brasil. Se utilizó para la colecta de datos una ficha con informaciones demográfico-clínicas y el Nursing Activities Score (NAS). En el análisis de los datos se utilizo estadística descriptiva, inferencial y modelos de regresión linear. Resultados: La media del NAS en la unidad fue del 47,8% (11,5 horas). Pacientes con enfermedades oncológicas y hematológicas malignas demandaron mayor carga de trabajo de enfermería, comparados a aquellos con enfermedades no malignas (p=0,0034); los pacientes que murieron presentaron mayor puntuación de NAS, comparada con la de los Vol. 16, N.º 4supervivientes (p<0,0001); en la regresión linear, las variables, diagnóstico y condición de salida, determinaron un R de 0,26. Conclusión: Pacientes onco-hematológicos demandan asistencia semi-intensiva, información que ofrece subsidios al enfermero para planear recursos humanos en esta especialidad.RESUMO: Objetivo: Identificar os fatores relacionados à carga de trabalho de enfermagem gerada por pacientes onco-hematológicos hospitalizados.

Methods: Prospective cohort study conducted with 151 inpatients at a hematology/oncology unit of a university hospital in São Paulo, Brazil. Data were collected using a form with demographic-clinical information and the Nursing Activities Score (NAS). The collected data were analyzed using descriptive and inferential statistics and linear regression models. Results: Mean NAS in the unit was 47.8% (11.5 hours). Patients with malignant oncological and hematological diseases generated a higher nursing workload than patients with non-malignant diseases (p = 0.0034). Patients who died had higher NAS scores than survivors (p <0.0001). In the linear regression, the variables diagnosis and condition at discharge determined an R of 0.26. Conclusion: Hematology and oncology patients require high dependency care. This finding can support nurses when planning human resources in this specialty

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved

Growing knowledge: an overview of Seed Plant diversity in Brazil

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
