Contribuições da Teoria das Representações Sociais para (re)pensar o upcycling na área da Moda

This theoretical study aimed to provide reflections about the contributions of the Theory of Social Representations (TSR) to the approach of upcycling in ​​Fashion. The theoretical foundation is based on the conceptual elements of upcycling and TRS. The cut of the article is defined by the literature review on two topics, seeking to show its articulation. The literature shows the relationship of upclycling as sustainable development, in contrast to what is meant by “recycling”. In the psychosocial perspective of the TSR, as the subjects / groups elaborate representations about upclycling, mainly in the fashion area, it indicates an understanding of meanings that are constructed through communication, exposing specific interests and revealing cultural identities. The article seeks to awaken reflections that can support future empirical studies, since issues related to sustainability are increasingly present in training and in the world of fashion work, and the understanding of the meanings constructed by the various groups involved becomes relevant in this context.El estudio, de carácter teórico, tiene como objetivo proponer reflexiones sobre los aportes de la Teoría de las Representaciones Sociales (TRS) al abordaje del upcycling en el ámbito de la Moda.

A fundamentação teórica está pautada em elementos conceituais do upcycling e da TRS. O recorte do artigo se define por revisão de literatura não exaustiva sobre os dois temas, buscando mostrar sua articulação. A literatura mostra a relação do upclycling com o desenvolvimento sustentável, se contrapondo ao que se conhece por “reciclagem”. Na perspectiva psicossocial da TRS, a maneira como sujeitos/grupos elaboram representações sobre upclycling, particularmente na área da Moda, indicam compreensões sobre significados que são construídos por meio das comunicações, expondo interesses específicos e revelando identidades culturais. O artigo busca despertar reflexões que poderão respaldar futuros estudos empíricos, uma vez que temas relativos à sustentabilidade estão cada vez mais presentes na formação e no mundo do trabalho da Moda, e a compreensão de significados construídos por diversos grupos envolvidos se torna relevante nesse contexto

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Diagnóstico ambiental de nascentes na bacia hidrográfica do Rio Piauí, Alagoas

It is notorious the concern with the water supply in the world, since this is a finite resource. The lack of rain, mainly in the Northeast region, allied with the environmental degradation of our water courses, has been contributing even more to the worsening of this crisis. Therefore, the objective of this work was to identify the tributaries of the Piauí River in Alagoas in the middle and lower portions of its watershed, performing its georeferencing and then a macroscopic analysis of each source. The diagnosis was made in the months of August, September and October of 2015, a survey of all the springs of this hydrographic region was carried out and they were qualified according to their degree of preservation. In order to carry out this qualification, on-site visits were carried out at these sources and, by completing a form, together with the sum of the points, it was possible to classify the degree of preservation of each source. The environmental report shows a worrisome situation from the macroscopic point of view, since none of the springs diagnosed was classified as having an excellent degree of preservation, and more than 70% of them were classified as poorly preserved.É notório a preocupação com o abastecimento de água no mundo, já que este é um recurso finito. A falta de chuva, principalmente na região Nordeste, aliada com a degradação ambiental dos nossos cursos d’água, vem contribuindo ainda mais para o agravamento dessa crise. Sendo assim, objetivou-se com este trabalho identificar as nascentes afluentes do Rio Piauí em Alagoas nas porções média e baixa de sua bacia hidrográfica, realizando seu georreferenciamento e em seguida uma análise macroscópica de cada nascente. O diagnóstico foi realizado nos meses de agosto, setembro e outubro de 2015, foi realizado um levantamento de todas as nascentes dessa região hidrográfica e as mesmas foram qualificadas de acordo com seu grau de preservação. Para a realização dessa qualificação, foram realizadas visitas in loco a essas nascentes e através do preenchimento de uma ficha, juntamente com o somatório dos pontos, foi possível classificar o grau de preservação de cada nascente. O relatório ambiental mostra uma situação preocupante do ponto de vista macroscópico, pois, nenhuma das nascentes diagnosticadas, foi classificada em um ótimo grau de preservação, e mais de 70% delas foram classificadas em um estado de preservação ruim a péssimo

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
