Insights from applying different assessment methods for metals resource use
No full textSociety’s increasing metal demand raises a number of concerns. In the shorter term, there may be risks to for constraints on expanding extraction to meet a rapidly increasing demand, causing supply disruptions and price volatility which especially affects import-dependent regions. The ongoing transition to renewable electricity production based on wind and sun and to electrified vehicles may even be delayed because of lack of required metals. In the longer term, continued extraction depends on decreasingly concentrated ores and may risk to eventually cause depletion. Metal use is also associated with significant environmental impacts, through life cycle energy use and locally from mining. The social impacts of so-called conflict minerals are undisputable. Companies and public policy makers wishing to act on these concerns are faced with a multitude of issues and potential solutions, such as circular economy, may involve trade-offs between different issues and consequently require decisions on what issues to prioritize. Ex-ante assessments can offer such decision-makers the opportunity to study potential implications of different actions before-hand. However, it may be challenging to discern the purpose of the multitude of methods that exist and what aspects of metal resources they in fact address. Furthermore, can methods be used in a complementary way or are they overlapping? Are they appropriate for any context? This contribution aims to present insights gained from having applied a selection of different assessments methods to study how circular economy solutions affect metal use. The methods are life cycle assessment, criticality assessment, dynamic material flow analysis and circularity indicators. All are applied for studying various aspects of circular economy solutions for electric traction motors in passenger cars – an essential part of the drivetrain of all types of electric vehicles and one that requires several metals such as iron, copper, aluminium and rare earth elements. The methods have been applied in separate studies performed over several years (Huisman et al. 2017, André and Ljunggren 2020, Løvik et al 2021, Jerome et al. 2022) and have pointed to different potential actions to take for decision makers. In this contribution, the studies will be presented and compared to illustrate typical questions addressed regarding metal resource use and differences and similarities between methods. This may support a discussion on what methods to apply in what contexts as well as what methods to apply in a complementary manner, what methods to further integrate and what methods to develop. The goal is to support a purposive and more comprehensive and assessment of actions to reduce concerns about society’s metal resource use. References: André, H. and Ljunggren, M.

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Analysing future solid waste generation - Soft linking a model of waste management with a CGE-model for Sweden
No full textParallel to the efforts of the EU to achieve a significant and overall reduction of waste quantities within the EU, the Swedish parliament enacted an environmental quality objective stating that ‘the total quantity of waste must not increase …’ i.e. an eventual absolute decoupling of waste generation from GDP. The decoupling issue is ad-dressed, in the present paper, by assessing future waste quantities, for a number of economic scenarios of the Swedish economy to 2030 with alternative assumptions about key factors affecting waste generation and waste management costs. We use an integrated top-down/bottom-up approach by linking a CGE-model of the Swedish economy with a systems engineering model of the Swedish waste management system. In this way, we can in more detail consider the interaction between waste generation and waste management costs (waste disposal prices) when assessing future waste quantities. A relative decoupling of waste generation takes place in all scenarios, i.e. total waste quantities increase at a lower rate than GDP. Absolute decoupling, which re-quire total waste quantities to stabilize or to reduce, does not take place in any of the scenarios. This means that the present Swedish Environmental quality objective of stabilizing waste quantities is not met in any of the scenarios with total waste genera-tion levels of 110 per cent up to nearly 200 per cent of that in 2006. The overall impression from our analysis is that costs are high for reducing waste generation irrespective of the type of waste reduced. In other words, the waste treat-ment costs are low compared to the costs for reducing waste. This situation also means that the use of policy instruments, which induce substitution by increasing the price of waste disposal services, will have very small reducing effects on the generation of all types of waste unless the price increase brings about an introduction of waste preventing techniques and affect households in the direction of a less waste intensive behaviour. For example, the policy instruments used must affect the pattern of household consumption pattern more directly, as a differentiation of the value added tax, rather than to be directed towards the waste management sector. Economic policy instruments introduced in the waste management sector are more likely to affect the choice of waste management solutions than prevent waste generation. Linking a macroeconomic and a systems engineering model for waste manage-ment, gives us a tool useful also for capturing the macroeconomic effects, such as GDP growth and structural changes, when designing policy instruments intended to prevent waste generation or take waste management in a more sustainable direction.general equilibrium model; systems engineering; solid waste; waste management; waste generation; decoupling; EMEC; NatWaste; top-down/bottom-up; waste policy instruments

Imagens de Otto Maria Carpeaux: esboço de biografia
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2015.Este esboço de biografia procura citar algumas imagens de Otto Maria Carpeaux: construções biográficas de naturezas múltiplas, elaboradas em contextos, por atores e sob condições igualmente díspares. Está constituído a partir de uma visão crítica da História, o que permite que ?outras imagens?, fragmentárias e não monumentais, também tenham espaço. Em diálogo com o princípio da montagem, este esboço apresenta-se em duas partes. Na primeira, Imagens possíveis, estão citadas as imagens elaboradas em vida e post mortem acerca do austríaco-brasileiro que nasceu em Viena em 1900, se exilou no Brasil em 1939 e morreu no Rio de Janeiro, em 1978. Na segunda, Montagens possíveis, apresentam-se duas possibilidades de exercício biográfico: pela leitura alegórica do documentário O velho e o Novo (Otto Maria Carpeaux), entendido como instrumento de intervenção no contexto ditatorial brasileiro e de uma reelaboração biográfica concernentes às suas experiências europeias; e pelo Caderno de imagens críticas, registro dos encontros em Carpeaux pelo meio de imagens críticas produzidas a partir da cesura do presente.Abstract : This biographical sketch attempts to quote some images of Otto Maria Carpeaux: various types of biographical constructions, carried out in different contexts by disparate authors under conditions just as distinct. It stems from a critical view of history, allowing for ?other images? fragmented and non-monumental ? to share the space.In dialogue with the montage principle, this sketch has two parts. The first, Possible Images, quotes the images produced during and after the life of the Austrian-Brazilian, who was born in Vienna in 1900, went to Brazil in exile in 1939 and died in Rio de Janeiro in 1978. The second part, Possible Montages, presents two possibilities of a biographical exercise: through the allegorical reading of documentary O Velho e o Novo (Otto Maria Carpeaux), understood as an instrument of intervention in the Brazilian dictatorship context and as a biographical retelling of the author?s European experiences; and through my Scrapbook of Critical Images, a record of the encounters in Carpeaux through critical images produced from the caesura of the present
Maria José ao encontro de Tchekov
No full text“A Carta da Corcunda para o Serralheiro” (“Letter from the Hunchback Girl to the Metalworker”), signed by Maria José, was first performed in a theatre show in 1988 (by actress-director Maria do Céu Guerra), two years before the typescript was published in book form for the first time by Teresa Rita Lopes. The evidence upon which this article is built is that it was the theatre that revealed the dramatic destination of this singular epistle of the only female heteronym that Fernando Pessoa invented, which was also the last heteronym to be created by the author. The dramatic construction of Maria José can be approximated to the character-building strategies in Anton Chekhov’s realist dramaturgy, in a way that differs from Pessoa’s other dramaturgical experiences. The analysis of Chekhov’s ascendancy over Stanislavski’s research, as well as the importance of Schopenhauer’s conception of the tragicomic, which is simultaneously projected onto Chekhov’s theatre and Maria José’s profile, are favourable lines of reading for this rapprochement between Pessoa and the Russian fiction writer and playwright. Pessoa’s readings of Chekhov’s texts (such as the play Uncle Vania and the short story “Vanka”) provide relevant data for assessing the magnitude of this encounter.“A Carta da Corcunda para o Serralheiro”, assinada por Maria José, começou por ser difundida num espectáculo de teatro em 1988 (pela actriz-encenadora Maria do Céu Guerra) dois anos antes de o dactiloscrito se ver publicado em livro, pela primeira vez, por Teresa Rita Lopes. Parte-se da evidência de ter sido o teatro a revelar a destinação dramática da epístola singular do único heterónimo mulher que Fernando Pessoa inventou, que terá sido também o último a ser criado pelo autor. A construção dramática de Maria José pode ser aproximada às estratégias de construção de personagem na dramaturgia realista de Anton Tchekov, de um modo que se distingue de outras experiências dramatúrgicas de Pessoa. A análise do ascendente de Tchekov sobre as pesquisas de Stanislavski, bem como a importância da concepção de tragicómico em Schopenhauer, que se projecta em simultâneo sobre o teatro de Tchekov e sobre o perfil de Maria José, são linhas de leitura propícias para esta aproximação entre Pessoa e o ficcionista e dramaturgo russo. As leituras de textos de Tchekov por parte de Pessoa (como o caso da peça Tio Vânia e o conto “Vanka”) fornecem dados relevantes para avaliar a magnitude deste encontro
O negro como personagem na literatura infantil, na obra de Maria Rita Py
No full textTried to when analyzing the works of Coleção História da Vó Preta, of the Santa Mariense author Maria Rita Py, the representation of black people, showing how the issues surrounding it in society, his yearnings, sorrows, lived since last century , are present in contemporary children's literature. The literature has shown an increasing concern in presenting a cultural identity that expresses the relationship of social inclusion. The Brazilian reality shows that the black, after the liberations of slaves, and most recently with the growth of the black movement, assumed a new vision, creating a new discourse in this literature, when passing to be personage of the transformation of black spirit (sense). It is in this context that the black literature of Maria Rita Py inserts, dedicated to child audience, search for solutions to solve the problems of this personage such as frustration, rejection, desire to be white, doubts and anxieties of children black in society, affect self-esteem and identityProcurou-se ao analisar nas obras da Coleção História da Vó Preta, da autora santa-mariense Maria Rita Py, a representação do negro, demonstrando como as questões que o envolvem na sociedade, seus anseios, mágoas, vividas desde o século passado, estão presentes na literatura infantil contemporânea. A literatura tem evidenciado uma preocupação cada vez maior em apresentar uma identidade cultural que expresse as relações de inclusão social. A realidade brasileira mostra que o negro, após a libertação dos escravos, e mais recentemente com o crescimento do movimento negro assumiu uma nova visão, criando um novo discurso nessa literatura, quando passa a ser personagem da transformação da consciência negra. Neste contexto que se insere a literatura negra de Maria Rita, dedicadas ao público infantil, destaca-se a preocupação em buscar soluções para resolver os problemas dos seus personagens tais como: frustração, rejeição, desejo de ser branco, dúvidas e os anseios de crianças negras na sociedade, mas que afetam a auto-estima e a sua identidade
