No full textIn this contribution, Giulia Zanon investigates the use of detail as a scholarly tool in Warburg’s corpus. In the first phase of an ongoing study, the author makes a recognition of the cases in which the detail of an image in the Atlas is enlarged and juxtaposed to its original, highlighting the different visual strategies exploited by the scholar to develop and expose his research themes
Some Remarks on Bruce Ackerman's "Revolutionary Constitutionalism : Charismatic Leadership And The Rule Of Law"
No full textThe contribution aoffers a short analysis of Bruce Ackerman's book "Revolutionary Constitutionalism: Charismatic Leadership and the Rule of Law". In particular the Author focuses on two key issues of Ackerman's analysis. The first relevant aspect is the role played by the judiciary, especially by constitutional and supreme Courts, in the revolutionary dynamic. The second one is the cultural diagnosis of the EU crisis and of its legitimacy, read in the light of the different constitutional paths (elite-driven, revolutionary and establishmentarian) taken by EU Member States
Petrographic, mineral chemistry and geochemistry of dykes swarms in the Piratini and Pinheiro Machado regions, RS
No full textEsta tese apresenta os resultados dos estudos petrográficos, geoquímicos e de química mineral dos enxames de diques ácidos e básicos e suas encaixantes graníticas associadas ao Batólito Pelotas nas regiões de Piratini e Pinheiro Machado, RS. Os dados obtidos apontam para a existência de dois tipos de diques contemporâneos, ácidos e básicos, gerados aparentemente por processos e fontes magmáticas distintas, com os primeiros sendo associados ao magmatismo da fase final (Granitos da Suíte Dom Feliciano) do Batólito Pelotas, desenvolvido já em regime tectônico extensional. Os diques básicos, apesar da composição distinta, mostram evidências de campo e petrográficas da existência de mistura de magmas, sugerindo contemporaneidade com os diques ácidos. A biotita é o principal mineral máfico dos diques ácidos, enquanto o piroxênio ao lado do plagioclásio mais cálcico (conteúdos mais elevados em moléculas de anortita) aparece associado aos diques básicos, sugerindo que o magmatismo de cada dique foi gerado em condições termodinâmicas e níveis crustais bastante diferentes. Os aspectos de campo e as texturas observadas nos granitos encaixantes mostram a existência da superposição de deformação no estado sólido, tanto em condições dúcteis quanto em condições rúpteis, deformações estas que não foram observadas nos diques. Contudo, as texturas observadas nos diques (micrográfica, mirmequítica, dentre outras) sugerem a presença de líquido residuais ricos em sílica interagindo com minerais de mais alta temperatura já cristalizados. Os dados geoquímicos caracterizam para a região de Piratini diques de composição riolito, traquito e basalto, enquanto para a região de Pinheiro Machado caracterizam diques de composição riolito, traquidacito, dacito, latito e basalto. O mg# revela que os diques ácidos da região de Piratini são mais evoluídos do que as demais rochas estudadas. Os riolitos e traquitos de Piratini têm características de um magmatismo alcalino, e os basaltos, de magmatismo transicional com afinidade alcalina. Os riolitos, dacitos, latitos e traquidacitos de Pinheiro Machado caracterizam-se como magmatismo cálcio alcalino alto-K e, moderadamente alcalino, com o basalto mostrando-se cálcio alcalino. Os diques ácidos de ambas as regiões estudadas representam um conjunto relativamente homogêneo com relação aos conteúdos dos elementos terras raras, e mostram conteúdos mais acentuados em ETR leves, anomalias fortemente negativas de Eu e valores baixos de ETR pesados, sugerindo fracionamento pelo feldspato alcalino. Os diagramas multi-elementares mostram padrão similar entre os diques ácidos e os granitos, com anomalias negativas em Ba, Sr, Eu, Ti, Sc e Ni, enriquecimento em relação ao condrito em K, Rb, Zr, Y e Tb, enquanto o padrão dos diques básicos apresenta anomalias positivas em Ba, Ti, Sr, Eu e La, sendo levemente enriquecidos em relação ao condrito em K, Nd e Zr. A anomalia positiva em Eu pode ser explicada pela presença de anfibólio. A provável correlação dos diques ácidos com as suítes graníticas mais jovens do Batólito Pelotas sugere tratar-se de um magmatismo com características tectônicas tardi-a póscolisionais ao ciclo brasiliano.New petrographic, geochemistry and mineral chemistry data from acid and basic dyke swarms, associated to the Pelotas Batholith in the Piratini, Pinheiro Machado regions, within the Rio Grande do Sul state are presented in this work. The obtained data suggest that the two types of dykes were generated by different magmatic sources and processes, within an extensional setting that was linked to the Pelotas Batholith. These data suggest also an affinity between the acid dykes and granites from the Dom Feliciano Suite. The basic dykes show different compositions. Field and petrographic evidences shown the existence of magma mixing, suggesting contemporaneity with the acid magmatism. Biotite is the mafic mineral of the acid rocks, whereas pyroxene and calcic plagioclase are the minerals of the basic rocks and together suggest that the magmatism was formed within different thermodynamic and crustal level situations. Field and structural characteristic of the host granitoids show solid-state superimposed deformations within ductile and ruptil regimes, a situation that was not seen in the dykes. Some dykes shown textures mirmekite and graphic suggesting the presence of residual liquid in contact with already crystallized higher temperature minerals. Geochemical data shown that the Piratini dikes are ryholites, trachites, and basalts, whereas of the Pinheiro Machado are ryholites, trachyandesites, dacites, lathites and basalts. Mg# suggest that Piratini acid dikes are more evolved than the other rocks. Ryholites and trachites from Piratini have alkaline to transitional characteristics. Ryholites, dacites, lathites and trachyandesites from Pinheiro Machado are high-k calc-alkaline to moderately alkaline, with the basaltic types showing calc-alkaline nature. The acid dykes of both regions up present one group of rocks relatively homogeneous with relation the rare earth element (REE) values, showing values more pronounced in light RRE, largely negative Eu anomalies and values low in heavy REE, suggesting fractionation of alkaline feldspar. Multielementary diagrams of the studied rocks shown similar pattern between the acid dykes and granites, with negative anomalies in Ba, Sr, Eu, Ti, Sc and Ni, and enrichement in relation to the chondrite in K, Rb, Zr, Y and Tb, whereas the basic dykes pattern shown positive anomalies in Ba, Ti, Sr, Eu and La, being lightly enriched in K, Nd and Zr. Positive Eu anomalies may be interpreted by presence of amphibole. The probable correlation of acid dykes with newer granitic suites of the Pelotas Batholith suggests magmatism with tectonic characteristics late and post-collisionals the Brasiliano Cycle

The Sorrow of Odin the Goth: gli dèi nordici nella ricezione di William Morris
No full textIl saggio esamina la cosiddetta produzione nordica dell'intellettuale vittoriano William Morris. Dopo aver presentato l'avvicinamento di Morris alla materia nordica e il suo spiccato interesse per le saghe, l'autore concentra la propria attenzione sulla rappresentazione degli dèi germanici nelle opere di Morris. Se ne ricava una lettura di umanizzazione delle divinità che vengono avvicinate alla realtà umana, nelle sue sofferenze ma anche nella sua resistenza alle vicissitudini della vita con quello spirito eroico che tanto affascinava Morris anche nei personaggi delle saghe nordiche. Sono offerti anche estratti di traduzione da The Lovers of Gudrun.The essay examines the so-called Nordic production of the Victorian intellectual William Morris. After presenting Morris's approach to Nordic subjects and his marked interest in sagas, the author focuses on the representation of the Germanic gods in Morris's works. The result is a reading of the humanisation of the divinities, which are brought closer to human reality, in their suffering but also in their resistance to the vicissitudes of life with that heroic spirit which so fascinated Morris even in the characters of the Nordic sagas. Translation extracts from The Lovers of Gudrun are also offered
Revisão sistemática de Dissertações do PROFMAT: um diálogo entre combinatória e tecnologias digitais
No full textIn this article, seeks to answer the following questions: How do the theses of the Professional Master’s Program in Mathematics in the National Network (PROFMAT) from 2016 to 2020 deal, in basic education, with the solving of combinatorial analysis problems mediated by digital technologies? What contributions can a systematic review of these theses offer to research on this topic in Brazil and to classroom practices? A series of analyzes resulting from a systematic bibliographic review (Botelho, Cunha & Macedo, 2011; Romanowski & Ens, 2006) of PROFMAT theses produced in the period from 2016 to 2020 is presented. Gravina and Santarosa (1998), Onuchic (1999), Alevatto (2005) and Zanon (2019) were used to study nine productions, in which the understanding of combinatorial analysis and problem solving, and the presence of digital technologies were analyzed. Furthermore, the methodological aspects of the investigations and the products that each author developed were investigated. The results of the analyzes allowed to affirm the existence of a conflict in the understanding of what would be the problem solving, as well as the presence of technologies as a support for the application of the elaborated products.Neste artigo, busca-se responder às seguintes questões: Como as dissertações do Programa de Mestrado Profissional em Matemática em Rede Nacional (PROFMAT) de 2016 a 2020 tratam, na educação básica, a resolução de problemas de análise combinatória mediada pelas tecnologias digitais? Quais contribuições uma revisão sistemática dessas dissertações pode oferecer à pesquisa sobre essa temática no Brasil e às práticas de sala de aula? Apresenta-se uma série de análises decorrentes de uma revisão bibliográfica sistemática (Botelho, Cunha & Macedo, 2011; Romanowski & Ens, 2006) de dissertações do PROFMAT produzidas no período de 2016 a 2020. Recorreu-se a Gravina e Santarosa (1998), Onuchic (1999), Alevatto (2005) e Zanon (2019), para estudar nove produções, nas quais foram analisados principalmente as compreensões sobre análise combinatória e resolução de problemas, a presença das tecnologias digitais nas pesquisas, os aspectos metodológicos das investigações e os produtos que cada autor elaborou. O resultado das análises permitiu afirmar a existência de um conflito na compreensão do que seria a resolução de problemas, bem como a presença das tecnologias como suporte para a aplicação dos produtos elaborados
Fabula rasa: Gamifying a storytelling platform to enhance proactive science communication from TU Delft researchers
No full textThis research project proposes a theoretical gamified design of a storytelling platform to engage TU Delft researchers into proactive submission of story ideas to co-create online storytelling for wide audiences. While universities have focused on improving communication with the general public in the past decades, researchers may still find barriers to engage in public communication of science. One of these barriers is proactive media contact, as the scientific community may perceive it as outside of the researchers’ role and subject the “transgressor” to informal peer-based sanctions. By assessing a sample of TU Delft researchers’ attitude towards an online TU Delft non-profit storytelling platform for internal and external communication similar to the target one, response efficacy proved to be the primary variable to motivate TU Delft researchers to engage in co-creation of online storytelling. The findings further confirm existing theories that younger and more intrinsically motivated researchers seem more willing to engage in online storytelling compared to older and more extrinsically motivated peers. The study translated these guidelines into a gamified design based on graph force models that challenge researchers to create tags related to their story, and form connections with peers within the TU Delft. To access these functionalities, TU Delft researchers must register to the platform by submitting a story idea, e.g. related to their researcher or field of study, and be willing to co-create online storytelling if their story is chosen. The design targets different groups of users by balancing the experience through the Octalysis framework, and implementing social points, competitions among faculties and badges. According to an evaluation with the case owner and a gamification expert of the first iteration of the design, rewarding the submission of stories with a network, seem effective in engaging TU Delft researchers to submit story ideas proactively and enhance collaboration and innovation with the TU Delft.Applied Sciences | Science Communicatio
