Abstract This article analyzes the representations of motherhood at the beginning of the 20th century in Chile, focusing on its emotional configuration. Through a case study of parricide, it observes how the justification of male violence added a new discourse to validate itself in the public space, from female sexual transgression to the breach of maternal duties. The symbolic recovery of the "Mater dolorosa" model -based on a religious-Christian reference- was part of a strategy to reinforce the traditional feminine ideology aimed particularly at elite women in a context in which gender norms were discussed by women in this social sector. The emotional idealization of motherhood not only implied the reinforcement of the synonymy between maternity and femininity, but also the valuation of female passivity in the face of suffering and male violence.

Resumo Este artigo analisa as representações da maternidade no início do século XX no Chile, centrando-se na sua configuração emocional. Através do estudo de um caso de parricídio, observa-se como a justificação da violência masculina acrescentou um novo discurso para se validar no espaço público, desde a transgressão sexual feminina até à violação dos deveres maternais. A recuperação simbólica do modelo "Mater dolorosa" - assente numa referência religiosa-cristã - fez parte de uma estratégia de reforço da ideologia feminina tradicional dirigida sobretudo às mulheres da elite, num contexto em que este mesmo sector discutia as normas de gênero. A idealização emocional da maternidade implicou não só o reforço da sinonímia entre este conceito e o de feminilidade, mas também a valorização da passividade feminina perante o sofrimento e a violência masculina.

Resumen En este artículo se analizan las representaciones de la maternidad a inicios del siglo XX chileno, deteniéndose en su configuración emocional. A través del estudio de un caso de parricidio se observa cómo la justificación de la violencia masculina sumó un nuevo discurso para validarse en el espacio público, desde la transgresión sexual femenina al incumplimiento de los deberes maternos. La recuperación simbólica del modelo de la “Mater dolorosa” –fundada en un referente religioso-cristiano–, fue parte de una estrategia de reforzamiento del ideario tradicional femenino dirigido particularmente a las mujeres de elite, en un contexto en el cual ese mismo sector discutía las normas de género. La idealización emocional de la maternidad no solo implicó reforzar la sinonimia entre este concepto y el de feminidad, sino también la valoración de la pasividad femenina ante el sufrimiento y la violencia masculina.

ABSTRACT Objectives: To systematize the scientific literature about the study of special document collections available in open access data sources. Methods: The scoping review is used as a methodological tool. The SALSA framework and the PRISMA-ScR template are applied. The exploratory systematic review in Google Scholar, Dimensions, and Academia.Edu is complemented with a bibliometric study. The conjunction of both contributes to a more holistic approach to the object of study. Results: The exploratory systematic review and the bibliometric analysis allowed identifying the characteristics and/or distinctive features of the domain in question from the analysis of the content of the scientific literature. A terminological diversity (homonymy, synonymy, polysemy) was obtained around the denomination of the same document/collection. The mapping of the coverage and the thematic profile determined the existence of a wide thematic configuration and the genesis of proposals for the analysis of these collections associated with a thematic front that favors the application of Digital Humanities. Conclusions: The visualization of the elements, obtained from the review, reveals the ascending evolution of methodologies that -from the CI- pursue the creation of alternatives for the decoding of the documents that make up the special collections using a new perspective that offers the benefits of greater inclusivity, homogeneity, and social responsibility.

ABSTRACT We present an updated, commented, and revised catalog for the Brazilian cuckoo wasps (Hymenoptera: Chrysididae) and pay tribute to Adolph Ducke’s 1913 monographic work on the Brazilian fauna of these wasps titled “As Chrysididas do Brazil.” We document all 159 chrysidid species known to occur in Brazil, classified into 18 genera representing three subfamilies: Amiseginae, Chrysidinae, and Cleptinae. We detail all synonyms, provide geographical distribution for all recorded species, and compile host associations for 28 species in Brazil. Notes on type specimens and their depository collections are provided and complemented by images of 30 primary types. Additionally, we reinstated Exsecochrysis Linsenmaier from the synonymy with Pleurochrysis Bohart (rejected junior homonym) in place of Rhipidochrysis Rosa & Pavese, new synonym. All species previously treated as Pleurochrysis are transferred to Exsecochrysis. updated commented Hymenoptera (Hymenoptera Chrysididae Duckes Ducke s 191 As Brazil 15 1 subfamilies Amiseginae Chrysidinae Cleptinae synonyms 2 3 types Additionally rejected homonym Pavese synonym 19

ABSTRACT We present the taxonomic treatment of the fern family Blechnaceae for the Flora of Viçosa, based on typology, morphology, and field observations. We report the occurrence of seven species and two putative hybrids, belonging to three genera: Blechnum appendiculatum, B. ×caudatum, B. ×confluens, B. gracile, B. aff. juergensii, B. occidentale, B. polypodioides, Neoblechnum brasiliense, and Parablechnum brasiliense, comb. nov. Among these taxa, four names are rescued from synonymy: B. appendiculatum, B. ×confluens, B. juergensii and P. brasiliense (this, with a new combination into Parablechnum). The putative hybrids, B. ×caudatum and B. ×confluens, are formed by the crossing of B. gracile × B. occidentale, and B. occidentale × B. polypodioides, respectively - as suggested by our observations in the field, morphological intermediancy, and literature review. Future studies involving cytogenetics, genetics, and palynology will be needed to better understand the complex of Blechnum hybrids, including the best status for B. aff. juergensii.

ABSTRACT Introduction: In Information Science, multidisciplinarity is understood as the initial level for the Association of disciplines from different Sciences, which, as a representation of knowledge, aims to foster a common achievement, as we approach corporate governance. Treating the historical development of the term governance as a source of information to identify the specificity of the vocabulary, maintaining the literary guarantee, consolidates the formatting of the vocabulary itself, and may even derive connections by synonymy, homography or polysemy. All these arguments for the study of Governance information, preliminarily treated in a multidisciplinary way, can create the paths to seek new connections and integrations, allowing the creation of an informational context that fosters the state of governance practice. Objective: to create a conversational space on corporate governance to represent the formation of organized and correlated constructs from their properties and the informational flow in organizations. Methodology: literature review on the terms, meaning, use, properties, and resignification of content applied to governance, considering the terminological specificity, literary guarantee, deductive method and techniques related to terminological analysis for construct formation. Result: domain model in the context of governance applied to a corporate governance situation for Value Added analysis. Conclusion: defining an information representation model, composed of associated terms according to their properties and characteristics, extracted by coeval and chronological analysis of the use of the term governance, innovates Information Science in a multidisciplinary way, opening perspectives for its application in new social phenomena. Introduction Sciences which knowledge achievement guarantee itself synonymy polysemy way integrations practice Objective organizations Methodology meaning Result Conclusion characteristics phenomena

RESUMO Introdução: Na ciência da informação a multidisciplinaridade é entendida como o nível inicial para associação de disciplinas de diferentes ciências, que enquanto representação do conhecimento se propõe a fomentar uma realização comum, como abordamos a governança corporativa. Tratar o desenvolvimento histórico do termo governança como fonte de informação para identificar a especificidade do vocabulário, mantendo a garantia literária, consolida a formatação do vocabulário próprio, podendo derivar inclusive nas conexões por sinonímia, homografia ou polissemia. Todos estes argumentos de estudo da informação da governança, tratados preliminarmente de forma multidisciplinar, podem criar os caminhos para buscar novas conexões e integrações, permitindo a criação de um contexto informacional que fomente o estado da prática da governança. Objetivo: Criar um espaço conversacional sobre governança corporativa para representar a formação de constructos organizados e correlacionados a partir de suas propriedades e do fluxo informacional nas organizações. Metodologia: Revisão da literatura sobre os termos, o significado, o uso, as propriedades, e ressignificação de conteúdos aplicados à governança, considerando a especificidade terminológica, a garantia literária, o método dedutivo e as técnicas relacionadas à análise terminológica para formação de constructos. Resultado: Modelo de domínio no contexto da governança aplicado a uma situação de governança corporativa para análise do valor agregado. Conclusão: Definir um modelo de representação da informação, composto por termos associados em função de suas propriedades e características, extraídos por análise coetânea e cronológica do uso do termo governança, inova de forma multidisciplinar a ciência da informação, abrindo perspectivas para sua aplicação em novos fenômenos sociais.

Abstract: Background and Aims: Brenesia was originally proposed to accommodate an odd taxon among the Orchidaceae subtribe Pleurothallidinae. This species is characterized by its sessile leaves, secondary stems covered by inflated sheaths and, especially, by a raceme produced at the base of the secondary stem. A few more closely related taxa were discovered afterwards, but the generic name has mostly been placed under the synonymy of Pleurothallis. Recent DNA-based studies showed that Brenesia constitutes a monophyletic group within the genus Acianthera. We present here a review of Acianthera subgenus Brenesia, delimiting each species in the group and providing a key for their identification. Methods: Specialized literature, specimens deposited in scientific collections, in cultivation, or available at online databases were reviewed. For each species, their known localities were georeferenced and displayed on a map of Mexico and Central America using QGIS software; also, their conservation status was assessed according to the IUCN Red List. Key results: Acianthera subg. Brenesia includes five species distributed from central Veracruz, Mexico, to Panama. The species included in this group are Acianthera costaricensis from Costa Rica and Panama; A. herrerae from Chiapas, in Mexico, and Guatemala; A. johnsonii from Chiapas to Honduras; and A. sotoana from (Mexico) Veracruz and Oaxaca. For each taxon, a morphological description, drawing, photo, information concerning nomenclature, distribution, habitat, phenology, and comparison with similar taxa are provided. Acianthera rzedowskiarum is described as a new species from Chiapas, based on specimens previously confused with A. johnsonii. Conclusions: Acianthera subgenus Brenesia has a distribution restricted to Central America. Four of its five species are native to Mexico, and one is restricted to southern Central America.

Resumen: Antecedentes y Objetivos: Brenesia fue propuesto originalmente para acomodar un extraño taxón en la subtribu Pleurothallidinae de Orchidaceae. Dicha especie se caracteriza por sus hojas sésiles, tallos secundarios cubiertos por vainas infladas y, sobre todo, por un racimo producido en la base del tallo secundario. Luego se descubrieron algunos taxa similares adicionales, pero el nombre genérico por lo general fue incluido bajo la sinonimia de Pleurothallis. Estudios recientes basados en el ADN demostraron que Brenesia constituye un grupo monofilético dentro del género Acianthera. Aquí presentamos una revisión de las especies de Acianthera subgénero Brenesia, delimitando cada especie del grupo y proporcionando una clave para su identificación. Métodos: Se revisó literatura especializada, ejemplares depositados en colecciones científicas, en cultivo o disponibles en bases de datos en línea. Para cada especie sus localidades conocidas fueron georreferenciadas y sobrepuestas en un mapa de México y Centroamérica usando el software QGIS; además, se evaluó su estado de conservación de acuerdo con los Criterios de la Lista Roja de la UICN. Resultados clave: Acianthera subg. Brenesia incluye cinco especies distribuidas desde el centro de Veracruz, México, hasta Panamá. Estas especies son Acianthera costaricensis de Costa Rica y Panamá; A. herrerae de Chiapas, en México, y Guatemala; A. johnsonii de Chiapas a Honduras y A. sotoana de (México) Veracruz y Oaxaca. Para cada taxón se presenta una descripción morfológica, dibujo, foto, información sobre nomenclatura, distribución, hábitat, fenología y una comparación con taxones similares. Acianthera rzedowskiarum se describe como nueva especie basada en especímenes de Chiapas previamente confundidos con A. johnsonii. Conclusiones: Acianthera subgénero Brenesia tiene una distribución restringida a América Central. Cuatro de sus cinco especies son nativas de México y una se restringe al sur de América Central.

Abstract: Background and Aims: Since the publication of the book on Cuban marine macroalgae in 2015, new records have been found and taxonomic changes have been published. Therefore, the objective of this publication is to present a fifth updated systematic review, that includes Ochrophyta (Class Phaeophyceae), Rhodophyta and Chlorophyta. Methods: These results were recorded from information available in scientific papers, bachelor, master and doctoral theses, as well as scientific-technical reports from recognized specialists, considering those not included in the last review or that were published after 2015. The taxa were systematically ordered, the names and synonymy were reviewed according to Algaebase and the most recent scientific literature. Species were arranged alphabetically within each family. The distribution of each taxon was resumed for nine Ecological Districts (zones) of the Cuban shelf. Key results: An updated floristic list with 569 species, one subspecies, 25 varieties, and 21 forms is presented. Thirty-seven species are added to the previous review of which seven are new records for Cuba: Hydrolithon boergesenii, Neogoniolithon mamillare, N. propinquum, N. rhizophorae, Lithothamnion crispatum, Liagoropsis schrammii, and Peyssonnelia rubra. The distribution of these taxa in the nine zones of the Cuban shelf is provided. Conclusions: The zones showing more species have had a greater sampling effort or were predominantly rocky reef bottoms. However, macroalgae have not been inventoried in detail in the intertidal zone, bays, and coastal lagoons. Zones with fewer species coincide in having a narrower shelf where rocky substrates dominate, although macroalgae have not been inventoried in the intertidal zone, bays, and coastal lagoons.

Resumen: Antecedentes y Objetivos: Desde la publicación del libro sobre las macroalgas marinas de Cuba en 2015 se han publicado nuevos registros y cambios taxonómicos. Por lo anterior, el objetivo del presente trabajo fue presentar una quinta revisión sistemática actualizada, que incluye Ochrophyta (Clase Phaeophyceae), Rhodophyta y Chlorophyta. Métodos: Se recopiló la información disponible en publicaciones científicas, tesis de licenciatura, maestría y doctorado, e informes científico-técnicos de especialistas reconocidos, considerando aquellas que no fueron comprendidas en la revisión anterior o que fueron publicadas después de 2015. Los taxones encontrados fueron ordenados sistemáticamente, los nombres actualizados y la sinonimia revisada según AlgaeBase y la literatura más reciente. Las especies se ordenaron alfabéticamente dentro de cada familia. La distribución de cada taxón se resumió para nueve zonas consideradas como Distritos Ecológicos (zonas) de la plataforma cubana. Resultados claves: Se presenta un listado florístico actualizado con 569 especies, una subespecie, 25 variedades y 21 formas. Se añaden a la anterior revisión 38 especies, de las cuales siete son nuevos registros para Cuba: Hydrolithon boergesenii, Neogoniolithon mamillare, N. propinquum, N. rhizophorae, Lithothamnion crispatum, Liagoropsis schrammii y Peyssonnelia rubra. Se da la distribución de cada uno de estos taxones en las nueve zonas de la plataforma cubana. Conclusiones: Las zonas que presentaron más especies son aquellas que han tenido un mayor esfuerzo de muestreo o donde predominan los fondos rocosos arrecifales, aunque no se han inventariado detalladamente las macroalgas en la zona mesolitoral, bahías y lagunas costeras.

In hierdie artikel word 'n poging wat aangewend is om 'n model vir omvattende, eksakte en sistema-tiese voorstelling van 'n woord se sinonimie binne 'n woordeboekinskrywing daar te stel, veral by hoogs polisemiese woorde, bekend gestel. Dit is gebaseer op die komplementariteit van polisemie en sinonimie en 'n prototipegebaseerde siening van die laasgenoemde leksikale verwantskap. Die voorgestelde model word uiteengesit in vier stappe waarin 'n inskrywing in 'n nuwe sinoniem-woordeboek aangepas word: die analise van 'n woord se polisemiese struktuur, die samestelling van 'n woord se sinoniemstelle gesien as prototipegebaseerde kategorieë, die definiëring van sinonieme binne 'n stel en die strukturing en organisering van 'n individuele sinoniemstel en die volledige inskrywing. Volgens die model word die omvattendheid van sinoniemaanbieding daarin gereflekteer dat 'n inskrywing sinoniemstelle lys wat ooreenstem met verskillende betekenisse van die gegewe lemma sowel as in die tendens van elke stel om 'n wye reeks sinonieme te vertoon. Konsekwentheid en akkuraatheid in sinoniemvoorstelling word hoofsaaklik verkry deur die toepassing van prototipegebaseerde beginsels op die strukturing en organisering van sinoniemstelle en die definiëring van sinonieme. Die model ontsluit ook die moontlikheid van 'n deursigtige diagramgebaseerde visuele voorstelling van 'n woord se sinonimie in 'n elektroniese woordeboek wat 'n geriefliker visuele samestelling van groot hoeveelhede inligting aanbied. n omvattende sistematiese sistema tiese woorde gestel verwantskap sinoniemwoordeboek sinoniem struktuur kategorieë vertoon aanbied

This paper presents an attempt at providing a model for comprehensive, precise and systematic presentation of a word's synonymy within a dictionary entry, especially in the case of highly polysemous words. It is founded on the complementarity of polysemy and synonymy and a prototype-based view of the latter lexical relation. The proposed model is presented through four steps of tailoring an entry in a new dictionary of synonyms: the analysis of a word's polysemous structure, the compilation of a word's synonym sets viewed as prototype-based categories, the definition of synonyms within a set and the structure and organisation of an individual synonym set and the whole entry. Comprehensiveness of synonymy presentation according to the model is reflected in the fact that an entry lists synonym sets corresponding to different senses of the given headword as well as in the tendency for each set to offer a wide range of synonyms. Systematicity and precision in synonymy presentation are achieved primarily due to the application of prototype-based principles to the structuring and organizing of synonym sets and the defining of synonyms. The model also opens up the possibility of a transparent diagram-based visual representation of a word's synonymy in an electronic dictionary offering a more convenient visual organisation of large amounts of information. comprehensive words word s prototypebased prototype based relation categories diagrambased diagram information

Adicionalmente, se registra por primera vez en territorio argentino a Corythucha arcuata (Say), que se alimenta del roble común (Quercus robur L.), y se establece su conespecificidad con Corythucha bonaerensis Montemayor nov. sin. Se dan también nuevos registros distribucionales y de planta hospedante para Corythucha argentinensis Monte, y se discute la taxonomía de las especies argentinas del género. Se proveen imágenes de ejemplares recolectados y se dan sus caracteres diagnósticos. Se comenta brevemente la importancia de la aparición de estas especies en el país.

Abstract Atractus badius has a long and controversial nomenclatural history due to both its antiquity and the brevity of its original description. This species was described based on two syntypes from Java. Later, a lectotype was designated and the distribution range restricted to the Guiana Shield. Although this species has been repeatedly recorded throughout Amazonia and the Andes, these records have been erroneously assigned to A. badius because of a considerable level of confusion in the literature. We found 13 additional specimens of this poorly known snake, expanding our knowledge on its morphological variability, phylogenetic relationships and distribution. In this paper, we report new localities and data on meristic, morphometric, coloration, scales micro-ornamentation, osteology and hemipenial morphology to A. badius. We also determine the phylogenetic position of A. badius as nested in a composite Guiana Shield clade. In addition, we discuss recent advances on the systematics of Atractus and comment on some ‘new arrangements’ with respect to previously recognized species groups and available morphological evidence. Finally, we highlight the importance of accurate voucher identification before promoting taxonomic changes or implementing nomenclatural acts derived from new phylogenetic hypotheses, and notably propose the synonymy of the recently described A. pyroni with A. roulei.
