Bleyer, Sartori e Bertoni: singulares imigrantes colonizadores de ideias
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2013Esta investigação de doutorado se concentra na trajetória intelectual e de pesquisa de três imigrantes: o alemão George Carl Adolf Bleyer, o italiano César Sartori, médicos, e o botânico suíço Moisés Santiago Bertoni. A tese procura mostrar que esses protagonistas não eram somente imigrantes exercendo profissões em país estrangeiro, vindos à América movidos pelos movimentos migratórios e de colonização, mas intelectuais que desenvolveram pesquisas, defenderam ideias, produziram textos, doaram conhecimentos. Foram imigrantes singulares, em tese, colonizadores de ideias. Entre suas pesquisas, o ponto em comum é a temática indígena, pano de fundo desta tese, que os coloca em um mesmo território intelectual, embora tenham transitado em regiões geográficas distintas. O recorte temporal compreende o final do século XIX a meados do XX, período que demarca a chegada e permanência definitiva desses imigrantes no Brasil e no Paraguai. Dentre os documentos analisados, estão cartas pessoais e profissionais, artigos publicados em jornais, relatos de viagens, fotografias e livros publicados. Esse conjunto de fontes permite adentrar nas redes de sociabilidade estabelecidas por Bleyer, Sartori e Bertoni com familiares, profissionais, intelectuais, com discussões políticas e sociais, e também permite desvelar o lado emocional, quando expressaram sentimento de utopia ao migrarem para a América. This doctorate investigation is focused on the intellectual and research trajectory of three immigrants: the German George Carl Adolf Bleyer, the Italian César Sartori, both physicians; and the Swiss botanist Moisés Santiago Bertoni. The thesis aims to show that these leading figures were not only immigrants practicing their professions in a foreign country, coming to the Americas influenced by migration and colonization movements; but intellectuals who have developed researches, defended ideals, produced texts, donated knowledge. They have been unique immigrants, in thesis, ideas colonizers. Among their researches a common point is the indigenous theme, a background for this thesis, which places them in a single intellectual territory, although they have passed through distinct geographic regions. The time frame includes the late of the 19th century and mid-twentieth century, a period which marks the arrival and settlement of these immigrants in Brazil and Paraguay. Among the analyzed documents there are personal and professional letters, articles published in newspapers, travel reports, photographs and published books. This set of sources allows to penetrate the networks of sociability established by Bleyer, Sartori and Bertoni with relatives, professionals, intellectuals, social and political discussions, as well as with their emotional side, when they have expressed an utopia feeling while migrating to the Americas

Locus typicus: “… Genève au bord du lac…”. Type material: MHNG; syntype, ♂ imago; 620 Genthod 48 Genève, coll. Pictet / Gthod, 27.7 [written by F.-J. Pictet, probably giving the place (Genthod) and the date (July 27) of collecting]. – MHNG; syntype, ♂ imago bearing 4 labels (Fig. 2): 620 Genthod 48 Genève, coll.

Besides numerous subsequent misidentifications, there are 4 specimens that still bear a label handwritten by F.-J. Pictet and that were collected at Genthod, near Geneva. Only these 4 specimens can be considered syntypes of E. glaucops.Published as part of Sartori, Michel & Bauernfeind, Ernst, 2020, Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

Direct, Organocatalytic, Enantioseletcive Michael Reactions: Turning Common Michael Acceptors Into Vinylogous Carbon Nucleophiles
No full textalpha,beta-Unsaturated carbonyl or carbonyl-like moieties are usually envisaged as privileged electrophilic functionalities to be exploited, among others, in Michael addition reactions as well as synchronous or stepwise cycloadditions, opening the way to a wide range of highly valuable beta-functionalized scaffolds. However, behind this common reactivity pattern, an “umpolung” option can be unveiled when an enolizable alkyl group is present at the beta-position of the ylidene. In fact, using a suitable activating catalyst and capitalizing on the vinylogous pro-nucleophilic character of the alkyl group, an addition reaction of these substrates to proper electrophilic acceptors can be fostered to yield olefinic products functionalized at the most distant point of the molecule (C-gamma). We were able to proof this concept on several multidentate scaffolds, namely 3-alkylidene oxindoles,[1] alpha-alkylidene pyrazolinones[2] and dicyano-olefins,[3] by developing direct, organocatalytic, asymmetric, vinylogous Michael addition reactions using nitroolefins or unsaturated aldehydes as electrophilic counterparts. Based on stereocontrolled, covalent or non-covalent dual activation modes, the Cinchona- or prolinol-based organocatalysts performed well, promoting the reactions in high yields and with remarkable control of the regio-, diastereo- and enantioselectivity.

Potamanthus luteus (Linné, 1767). – Bae & McCafferty, 1991: 53 (synonymization). Accepted name: Potamanthus luteus (Linné, 1767). Locus typicus: “… aux environs de Turin...” [Italy]. Type material: Holotype [by monotypy], male imago, not traced. Remarks: Eaton (1884) already noticed that the type was missing in F.-J. Pictet’s collection in 1867. The synonymy proposed by Bae & McCafferty (1991) is consistent with the fact that P. luteus is the only Potamanthus species found throughout Europe.Published as part of Sartori, Michel & Bauernfeind, Ernst, 2020, Mayfly types and additional material (Insecta: Ephemeroptera) examined by F. - J.

Hitting and trapping times on branched structures
No full textIn this work we consider a simple random walk embedded in a generic branched structure and we find a close-form formula to calculate the hitting time H(i,f) between two arbitrary nodes i and j. We then use this formula to obtain the set of hitting times {H(i,f)} for combs and their expectation values, namely, the mean first-passage time, where the average is performed over the initial node while the final node f is given, and the global mean first-passage time, where the average is performed over both the initial and the final node. Finally, we discuss applications in the context of reaction-diffusion problems
Innovazione sociale tra vulnerabilità e resilienza delle comunità e dei territori
No full textil contributo ha l’ambizione di collegare il filone di ricerca sull’innovazione sociale a quello della sociologia dei disastri. Pur con specifiche differenze nei metodi di ricerca e nei modelli di spiegazione, la sociologia dei disastri concorda nel sottolineare la dimensione sociale, politica ed economica di eventi catastrofici (quali terremoti o alluvioni) - in aggiunta a quella naturale - nel delineare gli effetti e i danni complessivi. Le comunità rappresentano un attore primario, riconosciuto nel Sendai Framework delle Nazioni Unite, all'interno del ciclo dei disastri che si caratterizzano sia per vulnerabilità sia per resilienza, due aspetti da prendere congiuntamente in considerazione quando si vuole affrontare il tema della prevenzione e della riduzione del rischio a fronte di un disastro naturale. In questo senso, un approccio di innovazione sociale può contribuire a contestualizzare un 'wicked problem', quale quello rappresentato dai disastri, e contemporaneamente considerare le caratteristiche socioeconomiche della comunità che rappresentano realmente sia una fonte di vulnerabilità sia di resilienza, soprattutto quando incidono sul capitale sociale e il tessuto comunitario locale
