Palavras de Rosa: análise estilométrica da obra de João Guimarães Rosa
Get PDFTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2013.Nesta tese analisamos a obra literária de João Guimarães Rosa a partir da estilometria, com o objetivo de buscar as características do estilo rosiano que sejam possíveis de detectar por meio de ferramentas informatizadas de análise estatística. Nossa tese é verificar se esse tipo de estudo permite confirmar ou complementar intuições derivadas de leituras convencionais e, além disso, oferecer novos elementos textuais e estilísticos que nem sempre estão explícitos no texto. Para isso, privilegiaremos três estudos rosianos: Signo e sentimento (SPERBER, 1982) sobre a organização da linguagem de Rosa; O insólito em Guimarães Rosa e Borges (COVIZZI,1978), a qual propõe uma linha cronológica de expressão e explicação da obra rosiana; João Guimarães Rosa: travessia literária, (DANIEL, 1968), que afirma haver uma separação do léxico rosiano em duas fases: uma rural e outra urbana. A ferramenta estatística adotada foi o programa Hyperbase, de Étienne Brunet. Para os procedimentos de análises, trabalhamos com duas bases, uma com a cronologia de produção de escrita das obras e outra seguindo a cronologia de primeira publicação das obras, que foram respeitadas a fim de viabilizar a verificação da evolução e do crescimento do vocabulário do escritor. Levantamos muitas características do léxico rosiano, dentre elas verificamos que mais da metade de seu vocabulário não se repete; e que as obras de caráter sertanejo apresentam vocabulário menos diversificado. Por fim, veremos como Guimarães Rosa, ao final de sua carreira literária, tratou mais do seu material linguístico.Résumé : Cette thèse s'occupera de l'oeuvre littéraire de João Guimarães Rosa à partir de la stylométrie, ayant pour objectif la recherche de caractéristiques du style de l'auteur qui puissent être identifiées par moyen d'outils informatisés d'analyse statistique. Notre thèse consiste à verifier si ce type d'étude permet de confirmer ou d'enrichir des intuitions résultantes de lectures conventionnelles et aussi à offrir de nouveaux éléments textuels et stylistiques qui ne sont pas toujours explicites dans le texte. Pour cela, on privilégiera trois études sur l'écrivain : Signo e sentimento (SPERBER, 1982), texte sur l'organisation du langage de Rosa ; O insólito em Guimarães Rosa e Borges (COVIZZI, 1978), qui propose une frise chronologique de l'expression et explication de l'oeuvre de Rosa ; João Guimarães Rosa, travessia literária, (DANIEL, 1968), selon laquelle il y a deux phases concernant le lexique de l'écrivain : l'une rurale et l'autre urbaine. L'outil statistique adopté a été le logiciel Hyperbase, d'Étienne Brunet. Pour le procédés d'analyse, on a travaillé avec deux bases, à savoir, l'une qui contenait la chronologie de production d'écriture des oeuvres ; l'autre, la chronologie de la première publication des oeuvres, considérée dans ce travail afin de rendre possible une investigation effective de l'évolution et de l'expansion du lexique de l'auteur. Parmi la grande quantité de donnéés recuillies, on a pu constater que plus de la moitié de son lexique ne se répète pas. En outre, les oeuvres "sertanejas" présentent moins de variations lexicales. Pour conclure, on démontrera comment Guimarães Rosa, à la fin de sa vie, s'est occupé davantage de son matériel linguistique.Mots clés: Guimarães Rosa. Stylométrie. Statistique textuel
O Páramo é do tamanho do mundo: Guimarães Rosa, Bogotá, Iauratê
Get PDFTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2014.A obra de João Guimarães Rosa tem sido tradicionalmente lida entre aquelas que melhor sintetizaram, representaram e universalizaram no século XX determinadas realidades latino-americanas. Dessa maneira, tanto para a crítica como para a história literária, Guimarães Rosa figura entre aqueles autores que -antes da explosão mercadológica que conhecemos como boom- reativaram os assuntos, linguagens, personagens e espaços regionais ou interiores da América Latina, levando-os às formas literárias ditas universais. Para uma boa parte da crítica contemporânea, entretanto, a literatura que promoveu uma celebração do identitário nas décadas de 1960 e1970 na América Latina, teria servido como assassinato edípico substitutivo do pai europeu, como compensação simbólica perante aquilo que não se conseguiu além do literário. Nesse sentido, a literatura seria certamente um operador de barbárie, teria um papel fundamental na transição do Estado ao Mercado ao criar a impressão de uma autonomia que estava muito longe de se alcançar em tempos de atraso, dependência e opressão capitalistas. Entretanto, como esta tese tentará demonstrar, essa compensação simbólica não é atribuível exclusivamente à escritura literária, mas depende em grande medida dos protocolos que a interpretam. O arquivo do autor mineiro permite e exige uma leitura diferente desse corpus -portador de um mal-estar cultural que, longe de elaborar uma representação triunfalista de identidades nacionais, porta indícios de um saber trágico em que a razão e a loucura não são antitéticas mas complementares, assim como nele cultura e barbárie, vida e morte, trauma e sintoma, não estão claramente diferenciados. Há lugares da obra de Rosa que, longe de permitirem uma leitura autônoma, afirmam o seu valor pela contaminação ?não pela representação? de outros textos, eventos e culturas "periféricos" que exigem leituras em filigrana. O que há nesses textos, lido o conjunto a partir desses lugares? Afirmar-se-á à maneira de hipótese: diferimentos ativos sem um fundamento prévio, uma leitura da história como catástrofe que retorna tragicamente, uma compreensão do identitário como trânsito incessante entre o familiar e o estranho, como uma profunda e permanente comoção de tudo que corriqueiramente se associa ao próprio. Se pensada a escritura rosiana nesses termos, haverá também que pensá-la como o semblante de algo que porta marcas provindas das ordens da sensibilidade e da percepção, ou seja, como imagem receptora/emissora de experiência. A partir de um deslocamento do interesse crítico, do representacional ao vestigial, esta tese pretende evidenciar a maneira em que, muito além da criação de fábulas ou símbolos, ou da expressão da pura subjetividade -em tensão com uma realidade (histórica, política, social) de que o texto seria a ficção- Rosa faz a junção de elementos díspares em campos operatórios que reclamam os seus materiais a partir de presentes de urgência. Caracterizar-se-á, assim, a escritura de Rosa como um espaço intersticial, crivado de silêncios, de sintomas, de murmúrios subterrâneos que se dá como tarefa -à maneira benjaminiana- dar voz aos sem nome, multiplicar as singularidades que toca ou pelas que foi tocado. Em explosão, cruzado pelo desastre, ou seja, tão astral quanto monstruoso, o texto rosiano partilha com literaturas contemporâneas, ou com valores a elas atribuídos, numerosas características, dentre as quais se destacam: as marcas vestigiais de gentes liminares e singulares; a alegorese ou metonímia que circunscreve esses seres de maneira tal que tende a espectralizá-los como referentes; a colocação em crise das fronteiras entre noções como realidade e ficção (vida e morte, alto e baixo, próprio e estranho); e, finalmente, uma montagem de materiais heterogêneos que tende a manifestar sintomaticamente o mal-estar acima mencionado. Dessa maneira, mostrar-se-á que o corpus estudado é semblante de um real traumático e não simbolizável, e assim opera de uma maneira extática -levando o identitário ao umbral do alter, a literatura ao limite do sensível ou da imagem, a história a se revelar como retorno de uma catástrofe sem sentido
Lo spirito anarchico
No full textIl presente saggio introduce il volume di cui l'autrice è anche curatrice e traduttrice dei contributi internazionali ivi presenti. Dopo aver introdotto in Italia il contributo di Nathalie Zaltzman con la cura e traduzione del suo ultimo libro (Lo spirito del male, Borla, 2011), oltre che del saggio «Un problematico raccordo di memoria» (2010, in Per un’etica del disagio, Filema), De Rosa ne prosegue l'opera di diffusione ideando e dirigendo questa collaborazione internazionale che persegue un confronto scientifico tra autorevoli psicoanalisti del Quatrième Groupe ed il gruppo di ricerca interdisciplinare di cui è animatrice, "Rileggere il disagio", da tempo impegnato sul tema del disagio della civiltà e delle sue variazioni nell’orizzonte contemporaneo. Figura originale nel panorama psicoanalitico contemporaneo, Nathalie Zaltzman (1933-2009) ha segnato con Piera Aulagnier la vitalità scientifica del Quatrième Groupe, tra le società psicoanalitiche francesi contemporanee più impegnate nel campo della psicoanalisi applicata. Rinvigorendo il legame tra individuale e collettivo incardinato solidamente nella clinica psicoanalitica, e nella convinzione che la psicoanalisi vada intesa come strumento del lavoro di civiltà (Kulturarbeit), Zaltzman ha posto questioni coraggiose sul rapporto tra Kulturarbeit e male estremo: le potenzialità e le aporie del lavoro di civiltà; la resistenza dell’uomo di fronte alla barbarie; l’inumano nell’umano; il totalitarismo di eros e la funzione vitale di thanatos in situazioni estreme. Riferimento, quest’ultimo, al concetto di pulsione anarchica introdotto da Zaltzman che percorre carsicamente la sua intera produzione scientifica e che costituisce il fil rouge del saggio introduttivo di De Rosa che qui si presenta. Attraversando l’opera di Zaltzman e analizzando il dibattito scientifico della comunità psicoanalitica francese e canadese nei convegni e nei volumi a lei dedicati post mortem, De Rosa approfondisce il concetto di pulsione anarchica come operatore di resistenza di fronte alle forme di impossessamento totalitario nelle dimensioni del collettivo e dell’individuale. Siamo, dunque, in un’area di nicchia della ricerca umanistica, quella della ricerca psicoanalitica applicata alle questioni di civiltà, ma che appare non anodina per il suo sforzo di portare avanti uno sguardo integrato, interdisciplinare, sulle problematiche che funestano la nostra contemporaneità: l’avanzare dei fanatismi, le politiche totalitarie, le nuove forme di malessere che destrutturano le società civilizzate

Chrysis (Chrysis) pulchella group: Linsenmaier 1959a: 93 (key), 103 (diagnosis). Chrysis pulchella group: Kimsey & Bohart 1991: 322 (key), 331 (Fig. 107o), 336 (Fig. 110h), 358 (diagnosis, discussion). Farhad et al. 2019: 1006 (diagnosis). Chrysis zaravshanica group: Tarbinsky 2002: 23 (description). Gender. Feminine. Type species. Chrysis pulchella Spinola, 1808, by present designation. Note. Some of the species included in this genus were previously included in Gonodontochrysis Semenov-Tian-Shanskij, 1954b, which is unavailable (see above). Linsenmaier (1959a) and Kimsey & Bohart (1991) included all members of Morphochrysis gen. nov. in the Chrysis pulchella species-group (Fig. 1). Tarbinsky (2002) described the Chrysis zaravshanica species-group based on a member of this genus (Chrysis personata Semenov, 1967 = Chrysis zaravshanica Tarbinsky, 2002 syn. nov.). Distribution. Palaearctic. Description. Species of medium to large size, with head distinctly larger than pronotum; first flagellomere elongate in both sexes (length/width ratio 2.5–3.2); scapal basin medially polished or slightly corrugated in the upper part, occasionally finely punctate in females; face usually finely punctate and covered by dense, adpressed whitish pubescence in males; transverse frontal carina strongly developed, broadly M-like, sometimes with distinct rami almost encircling anterior ocellus or delimiting anterior ocellar area; malar space as long as 1.0–1.5 × anterior ocellus diameter; radial cell open, with fore-wing radial sector short, 0.5–2.5 × anterior ocellus diameter away from wing margin; second metasomal tergum with weak to moderate longitudinal medial carina; third metasomal tergum with distinct pit row; lateral edges of third tergum with a small tooth, or angle, at or beyond the middle, followed by a slight concavity, more or less marked depending on species; third tergum apicomedially usually biconvex, rarely convex (Morphochrysis diadema) to nearly straight (Morphochrysis atechka and Morphochrysis intercurra) (Fig. 2); black spots on second sternum oval or rectangular, in some species close to each other or completely fused medially and covering large part of the segment (e.g. Morphochrysis pulchella and Morphochrysis calimorpha); male eighth sternite quadrangular, apically broad; male genital capsule with slender and elongate gonocoxa, apically curved; male and female internal segments unusually round shaped (Fig. 3). Finally, this genus is supported by molecular phylogenetic analyses as a distinct clade (Pauli et al. 2019). Hosts. Unknown. Distribution. The genus currently includes 33 species occurring all over the Palaearctic Region, in particular in dry, semi-desert and desert areas. However, preliminary molecular and morphological data suggest that some Nearctic species, currently included in Ceratochrysis Cooper, 1952, may also belong here. Species included. Morphochrysis adolescentula (Semenov-Tian-Shanskij, 1912) (Central Asia) (upgraded to species rank by Rosa et al. 2017a: 46); M. andradei (Linsenmaier, 1959a) (Iberian Peninsula); M. asahinai (Tsuneki, 1950) (Mongolia); M. atechka (du Buysson, 1898a) (North Africa); M. belokobylskiji (Rosa, 2019a) (Central Asia, Mongolia); M. buxtoni (Morice, 1921) (Iraq); M. calimorpha (Mocsáry, 1882) (replacement name for Chrysis dives Dahlbom, 1854, nec Lucas, 1849, see Rosa & Xu 2015) (West Palaearctic) (subspecies: M. c. siziliana Linsenmaier, 1959a); M. clivosa (Linsenmaier, 1959a) (Iberian Peninsula); M. cloe (Semenov-Tian-Shanskij, 1967) (Central Asia); M. diadema (Rosa, 2018c) (Central Asia); M. dives (Lucas, 1849) (North Africa); M. dusmetina (Bohart in Kimsey & Bohart, 1991) (replacement name for Chrysis dusmeti Trautmann, 1926, nec García Mercet, 1904) (Iberian Peninsula); M. flagrans (Semenov-Tian-Shanskij, 1967) (Caucasus, Turkey) (synonym: Chrysis turceyana Linsenmaier, 1959a); M. flamma (Semenov-Tian-Shanskij, 1954) (Tadzhikstan); M. foveata (Dahlbom, 1845) (North Africa) (see Rosa & Vårdal 2015); M. gamberoonensis (Farhad, Rosa & Talebi, 2019) (Iran, Saudi Arabia); M. gracilicornis (Semenow, 1892) (Central Asia) (synonym: Chrysis benjamini Semenov-Tian-Shanskij, 1967); M. hameri (Linsenmaier, 1994) (Arabian Peninsula); M. houbaraeensis Strumia & van Harten, 2020; M. intercurra (Linsenmaier, 1968) (Middle East); M. larochei (Linsenmaier, 1993) (Canary Islands); M. mosulensis (Linsenmaier, 1968) (Iraq); M. personata (Semenov-Tian-Shanskij, 1967) (upgraded to species rank by Rosa et al. 2017a: 46) (Middle East, Central Asia) (synonym: Chrysis zaravshanica Tarbinsky, 2002 syn. nov.); M. prodives (Linsenmaier, 1968) (North Africa); M. przewalskii (Radoszkowski, 1887) (Palaearctic China); M. pulchella (Spinola, 1808) (West Palaearctic) (synonyms: Chrysis sinuata Brullé, 1833; C. spinifera Abeille de Perrin, 1878; C. dives europaea Linsenmaier, 1959a); M. rubicunda (Semenov-Tian-Shanskij, 1967) (Central Asia); M. senescens (Semenov-Tian-Shanskij, 1967) (upgraded to species rank by Rosa et al. 2017a: 47) (Central Asia); M. retracta (Linsenmaier, 1959a) (Pakistan); M. tedshensis (Linsenmaier, 1968) (Central Asia); M. urakensis (Linsenmaier, 1968) (Pakistan); M. vahli (Dahlbom, 1854) (North Africa); M. ver (Semenov-Tian-Shanskij, 1967) (Central Asia) [the last doubtfully included]. Diagnosis. Members of the genus Morphochrysis resemble species of the Chrysis rufitarsis and Chrysis bihamata groups. Besides molecular differences, from a morphological point of view, the genus Morphochrysis is characterised by the internal segments with a rounded shape (vs. unmodified); male genitalia with gonocoxa apically bent (vs. straight); a tooth, or angle, on the lateral edge of the third metasomal tergum (vs. lateral edge straight or curved without basal tooth in the other two Chrysis groups); prominent transverse frontal carina (vs. weak); elongate first flagellomere (vs. shorter); fore wing with open radial cell, with radial sector ending slightly (0.5) to distinctly (2.5 anterior ocellus diameter) far from the wing margin. Discussion. Semenov-Tian-Shanskij (1954a) established Gonodontochrysis as a subgenus of Chrysis Linnaeus, 1761. However, being described with no generic diagnosis nor designation of type species, this name is unavailable (see above). Later, Semenov-Tian-Shanskij (1967) included in Gonodontochrysis other newly described heterogeneous species, for a total of 17 species and subspecies. In fact, his subgenus included species of five different species groups, namely bihamata, eborata, pulchella, rufitarsis and slava (Rosa et al. 2017 a, Rosa 2019b). Of the 17 taxa included by Semenov-Tian-Shanskij, C. aegle Semenov-Tian-Shanskij, 1967, C. capito Semenov-Tian-Shanskij, 1967, C. cephalotes Semenov-Tian-Shanskij, 1967, and C. kozlovi Semenov-Tian-Shanskij, 1967 belong to the C. bihamata group; C. eborata Semenov-Tian-Shanskij, 1967 belongs to the monotypic C. eborata group; C. dolens Semenov-Tian-Shanskij and Nikol’skaya, 1954, C. hafisi Semenov-Tian-Shanskij, 1967, and C. parthorum Semenov-Tian-Shanskij, 1967 belong to the C. rufitarsis group; and C. slava Semenov-Tian-Shanskij, 1967 belongs to the recently established C. slava group (Rosa 2019 b). Linsenmaier (1959a) established the pulchella group, including 10 species and 2 subspecies (Chrysis dives, C. dives europaea, C. retracta, C. asahinai, C. calimorpha, C. calimorpha siziliana, C. clivosa, C. pulchella, C. dusmeti, C. turceyana, and C. andradei). Kimsey & Bohart (1991) followed Linsemaier's interpretation, and included 21 members. Conversely, Linsenmaier (1999: 144) proposed the hydropica - pulchella group without any diagnosis. Rosa (2005: 55) subdivided this group again into two species groups (hydropica and pulchella), based on the shape of the genitalia and the internal terga and sterna (Rosa 2005: Figs 13, 15, 17). These differences are now considered diagnostic at genus level, the internal terga and sterna of the pulchella group being unique, and those of the hydropica group similar to other members of the genus Chrysis. Tarbinsky (2002) established the zaravshanica group, based on the newly described Chrysis zaravshanica Tarbinsky, 2002. After examination of the type, we propose a new synonymy, Chrysis personata Semenov-Tian-Shanskij, 1967 = C. zaravshanica Tarbinsky, 2002 syn. nov., and the merger of the zaravshanica group with the pulchella group.Published as part of Rosa, Paolo, Pavesi, Maurizio & Brothers, Denis J., 2023, Solving nomenclatural problems of genus-group names of the cuckoo-wasps (Hymenoptera, Chrysididae): objectively invalid and unavailable names, new type-species designations, new names, a new genus and new synonymies, pp. 1-50 in Zootaxa 5301 (1) on pages 31-34, DOI: 10.11646/zootaxa.5301.1.1, http://zenodo.org/record/801649
Consecration paths : Guimarães Rosa and critical judgement.
No full textQuando um autor expõe suas leituras e o modo como avalia diferentes práticas literárias, ele oferece uma oportunidade de compreendermos particularidades da prática literária, percebidas a partir de um ponto de vista interno. Mais que curiosa, essa visão interna nos dá pistas de mecanismos e escolhas relativas à percepção de valores literários. Os escritores, agentes literários dotados de um singular capital simbólico, podem perceber, elucidar e avaliar a literatura de seus contemporâneos, associando suas assinaturas aos nomes dos que desejam integrar o campo literário, por meio da crítica literária, desdobrando-se em um escritor-crítico. Outra forma de intervenção no campo literário por parte de escritores é a participação como jurados de concursos de literatura, cumprindo então um papel avaliativo. Guimarães Rosa não fazia crítica literária publicamente. Negava-se, sobretudo, a comentar seus contemporâneos, mas publicou textos em que ficcionalizou escritores, apresentando-os criticamente. Além desse jogo lúdico, pouco comentado (talvez pelo tom enigmático da brincadeira), exerceu em seus manuscritos algumas facetas de escritor-crítico, como vemos em suas anotações como jurado do prêmio Walmap (1966). Neste artigo, abordaremos textos sobre o concurso Humberto de Campos (1937), quando Guimarães Rosa foi julgado por Graciliano Ramos, e as anotações do prêmio Walmap, quando o autor mineiro assume o lugar de avaliador, observando quais critérios são reatualizados pelos dois escritores para a compreensão de seus contemporâneos. Além disso, abordaremos ospoucos textos assinados por Guimarães Rosa para apresentar escritores estreantes, nos quais podemos perceber outro éthos autoral em cena.When a writer exposes their readings and their way of analysing different literary productions, we have in hands a probing opportunity to comprehend particularities of the literary practice experienced by an inner point of view. More than curious, such point of view evidences mechanisms and choices related to the perception of literary values. Writers, as literary agents skilled with a symbolic and unique power, can elucidate, apprehend, and analyse their coeval colleagues’ literature. By becoming critical writers, they associate, through literary criticism, their character with the names of those who want to be part of the literary field. Another way for writers to act in the literary field is by being judges on literary contests, assuming an evaluative characteristic. Publicly, Guimarães Rosa was not a literary critic. He repudiated to comment his coetaneous colleagues. However, Rosa published texts in which he critically presented fictional authors. Besides this ludic game (uncommented probably due to his enigmatic game), he practiced some critical-writer aspects in his manuscripts, as in his notes on the Walmap Contest (1966), in which he was a judge. In this paper, we assess texts about both the Humberto de Campos Contest (1937) and the Walmap Contest, when Rosa took on the judge position. Our objective is to observe which criteria are revisited by both the authors to comprehend their coeval colleagues. At the same time, we analyse the few texts Rosa used to introduce the newcomer writers. In these few texts, we can perceive a different authorial ethos on the scene

Middle East, from Turkey to Palestine, Jordan and “ Syria ” (Levant, as Syria was potentially used to indicate the whole area). Etymology. The specific epithet rasmonti (masculine noun in genitive) is dedicated to Pierre Rasmont (Mons, Belgium), for his contributions to the study of the Hymenoptera and pollinators of Lebanon and of the Middle East in general. Remarks. Linsenmaier (1959) identified two similar species of the C. comparata group from East Mediterranean countries as Chrysis verna Dahlbom, 1854 (Figs 9A–9D) and C. handlirschi Mocsáry, 1889. He observed that these two species had previously been confused by Invrea (1943) and Balthasar (1953). Chrysis verna, described from Greece, was considered relatively rare (“ Ziemlich selten ”) (Linsenmaier 1959), but following research proved that it is a common and widespread species in Greece (“ In Griechenland eine der häufigsten Chrysis ”) (Linsenmaier 1968) and in Turkey (based on material deposited in NMLU and BZL). Chrysis handlirschi, described from Turkey, was instead considered a rare species (“ selten ”) (Linsenmaier 1959), actually known only from a few specimens deposited in his collection, BZL and NMPC. None of the authors cited above has examined the type series of these two species. The type of Chrysis verna is currently considered lost like other Dahlbom’s types described from the Loew collection (Rosa & Vårdal 2015; Rosa et al. 2017b, 2020a), whereas the type of Chrysis handlirschi has turned out to be a female of C. verna sensu auctorum (Rosa et al. 2020a). Consequently, Rosa et al. (2020a) proposed to synonymise Chrysis handlirschi with C. verna and suggested that C. handlirschi sensu Linsenmaier (1959) (Figs 7, 8) could represent an undescribed species. Two taxa were synonymised by Kimsey & Bohart (1991) with Chrysis handlirschi Mocsáry, 1889 and could have priority: Chrysis samia Bischoff, 1910 (Figs 9E–9G) and Chrysis handlirschi ab. astarte Balthasar, 1953. We (P.R.) checked the holotypes of both species. Chrysis samia is another synonym of Chrysis verna (Figs 9E–9G). On the other side, the name Chrysis handlirschi ab. astarte Balthasar, 1953 is unavailable, being described as an aberration (ICZN 1999, Art. 45.6.2). Therefore, we propose the new synonymy Chrysis verna Balthasar, 1953 = Chrysis samia Bischoff, 1910 syn. nov. and describe the taxon misidentified by Linsenmaier (1959) as Chrysis handlirschi as a new species, with the name Chrysis rasmonti Rosa, sp. nov. (Figs 7, 8). In recent years, a process of revision and stabilization of the nomenclature of members of this large species group has started with the neotype designation of Chrysis comparata Lepeletier, 1806 (Rosa & Xu 2015), followed by lectotype designations, synonymisations and revalidations (e.g. Chrysis analis Spinola, 1806, C. apiata du Buysson, 1900, C. caucasicola Balthasar, 1953, C. caucasicola Semenov-Tian-Shanskij, 1967, C. chrysostigma Mocsáry, 1889, C. distinguenda Dahlbom, 1854, C. excisa Mocsáry, 1889, C. lateralis Dahlbom, 1845, C. miegii Guérin-Méneville, 1842) (Rosa 2009; Rosa et al. 2013, 2015, 2017b; Rosa & Vårdal 2015; Rosa & Xu 2015). Chrysis rasmonti sp. nov. (Figs 7, 8) is similar to C. verna (Figs 9A–9D), yet males and females can be easily separated by elongate malar spaces (2.0 × MOD vs. 1.0 × MOD); metasomal sterna red (vs. green to blue); black spots on sternum II subrectangular (vs. subtrapezoidal). Moreover, females of C. rasmonti sp. nov. can be easily separated by body colour (compare Fig. 8A and 9A) with mesosoma green with a golden red stripe on posterior margin of pronotum (Fig. 8A) (vs. pronotum and lateral areas of mesoscutum shining green, contrasting with blue median area of mesoscutum, scutellum and metanotum (Fig. 9A)). Males can be easily recognised by body colour, elongate malar spaces, subrectangular black spots on sternum II, and finally by the different shape of the genital capsule (Figs 14A, 14B).Published as part of Boustani, Mira & Rosa, Paolo, 2022, Survey of cuckoo wasps of Lebanon (Hymenoptera: Chrysididae) with description of four new species, pp. 1-39 in Zootaxa 5104 (1) on pages 22-25, DOI: 10.11646/zootaxa.5104.1.1, http://zenodo.org/record/625770
Dynamic stability analysis and DQM for beams with variable cross-section.
No full textThe present paper deals with the dynamic behaviour of a clamped beam subjected to a sub-tangential follower force at
the free end. The aim of this work is to obtain the frequency–axial load relationship for a beam with a variable circular
cross-section. In this way, one can identify both divergence critical loads – where the frequency goes to zero – and the flutter
critical load – in correspondence with two frequencies coalescence. The numerical approach adopted for solving the
partial differential equation of motion is the differential quadrature method (henceforth DQM). This method was proposed
by Bellmann and Casti [Bellmann, R.E., Casti, J., 1971. Differential quadrature and long-term integration. J. Math. Anal.
34, 235–238] and has been employed recently in the solution of solid mechanics problems by Bert and Malik [Bert, C.W.,
Malik, M., 1996. Differential quadrature method in computational mechanics: a review. Appl. Mech. Rev., ASME, 49 (1),
1–28] and Chen et al. [Chen, W., Stritz, A.G., Bert, C.W., 1997. A new approach to the differential quadrature method for
fourth-order equations. Int. J. Numer. Method Eng. 40, 1941–1956]. More precisely, a modified version of this method has
been used, as proposed by De Rosa and Franciosi [De Rosa, M.A., Franciosi, C., 1998a. On natural boundary conditions
and DQM. Mech. Res. Commun. 25 (3), 279–286; De Rosa, M.A., Franciosi, C., 1998b. Non classical boundary conditions
and DQM. J. Sound Vibrat. 212(4), 743–748] to satisfy all the boundary conditions.
Some frequencies–axial loads relationships are reported in order to show the influence of tapering on the critical loads.

From Nonlinear Integrated Optics to Microresonator Frequency Combs
No full textPerhaps one of the most spectacular current applications of nonlinear integrated optics, a field
which was pioneered by George Stegeman more than thirty years ago [1], is that of nonlinear
microresonator based optical frequency comb light sources. Optical frequency comb sources are
characterized by a spectrum comprising many equally spaced components [2], and have a wide
range of scientific and technological applications. Although commercial comb generators are based
on mode-locked lasers and fiber supercontinuum generation, nonlinear integrated optics provides a
low-cost and chip-scale alternative, based on a low-power cw laser coupled into a high-Q
microresonator [3]. So far microresonator frequency combs have exploited the third order “Kerr”
nonlinearity, which permits to generate successive comb lines with a spacing equal to the resonator
free-spectral range via cascaded four-wave mixing [4-5]. Modeling of microresonator frequency
combs can be greatly simplified by a single partial differential equation approach [4-6], analogous
to the case of other coherently driven Kerr spatially diffractive [7] or temporally dispersive [8-9]
nonlinear cavities. In order to lower the threshold power and extend the spectral range of frequency
comb generation, for example into the visible or mid-infrared, while still using near-infrared cw
laser pumps, quadratic nonlinear cavities can be exploited [10]. These quadratic microresonator
frequency comb sources operate close to the phase-matching condition for the underlying quadratic
processes, and not in the cascading regime that reduces the dynamics to the Kerr case [11]. Quite
remarkably, a single time domain partial differential equation with an effective delayed third-order
nonlinearity was derived to describe with excellent accuracy the dynamics of quadratic frequency
comb generation [12-13]. In situations where multiple processes are present, and the frequency
combs generated around the interacting waves over multiple octaves overlap, we carried out
numerical modeling based on a single envelope equation approach [14].
