Species of the first group have flowers whose filaments are free for most of their length and fused at base, forming a basal ring, reduced connectives, and suborbicular to broadly elliptic anthers. As the filaments are free for half to most of their length, the short staminal ring that rest on the receptacle is hidden by petals at base, and the androecium apparently bears entirely free filaments from lateral and adaxial views. Also, the petals at anthesis are spreading over 50° to patent or even somewhat reflexed. This is a group of 11 species: the nomenclatural type <i>Grias cauliflora</i> Linnaeus (1759: 1075), <i>G. fendleri</i> Seemann (1854: 126), <i>G. neuberthii</i> J.F. Macbride, <i>G. peruviana</i> Miers, <i>G. colombiana</i> Cuatrecasas (1951: 96), <i>G. multinervia</i> Cuatrecasas, <i>G. haugthii</i> R. Knuth (1939: 31), <i>G. longirachis</i>, <i>G. ecuadorica</i>, <i>G. subbullata</i>, and <i>G. angustipetala</i>. The second group is characterized by flowers with the filaments of outer stamens fused 50 to 80 % of their length, exhibiting a conspicuously developed, fleshy, bowl-shaped staminal tube, and anthers ± oblong, with expanded, cucullate connectives with lateral flaps that enclose most of the thecae. The petals at anthesis are erect, sometimes reflexed inwards at apex to 50° spreading. This is a small group of three species, that includes: <i>G. theobromicarpa</i>, <i>G. purpuripetala</i>, and the new species <i>G. portillae</i>. For morphological differences among these three closely related species, see Table 1.</p> <p> <i>Grias portillae</i> can be distinguished from all other species in the genus, and is here recognized as a new taxon due to the presence of the following highly distinctive vegetative and reproductive characters: leaf blades with shortly caudate apex, flowers with the consistent combination of dark purple petals and creamish-white androecium, and mainly the presence of 18–21 stamens, the smallest number of stamens in the genus, with filaments inserted in only one level on top of rim, which is a unique feature in <i>Grias</i>, as the remaining species have filaments inserted in two to four levels.</p> <p> The androecium of <i>Grias portillae</i> externally may look similar to that of <i>G. theobromicarpa</i>; however, dissection of flowers reveals strong morphoanatomical differences between these two species, as the aforementioned fewer number of stamens (18–21 vs. 34–40), filaments inserted in only one level on top of rim (vs. filaments inserted in two levels, one level on rim, another level just below rim). Furthermore, the white to light yellow flowers of <i>G. theobromicarpa</i> was observed in all three known populations of this species (including the type, collected by the author and additional field images sent by Thomas Couvreur and from Los Cedros Biological Reserve; fig. 1).</p> <p> Among the species of <i>Grias</i>, <i>G. purpuripetala</i> is the only taxon with red-purple flowers in a genus previously known by having predominantly white to yellow flowers, sometimes tinged red (<i>G. neuberthii</i>). Although <i>Grias portillae</i> is a second species with purple petals, the latter cannot be confused with <i>G. purpuripetala</i> because of the consistent combination of dark-purple petals and creamish-white androecium, which is unique among species of <i>Grias</i>, while in <i>G. purpuripetala</i> the petals are red-purple and the androecium is rose to pink.</p> <p> Regarding the presence of colleters along the blades margin that were observed in <i>Grias portillae</i>, this inconspicuous feature has also been observed in herbarium material from all other species in the genus, with the exception of <i>G. multiflora</i>, due to limited access to herbarium specimens, and also in cultivated fresh material (from <i>Cornejo & Fernandez 6783</i>, GUAY, NY; Mori <i>et al</i>. 2023). Therefore, leaf blades with marginal colleters are here reported as an overlooked vegetative character at generic rank in <i>Grias</i>. Young blades with marginal colleters have been also observed by the author in several species of <i>Gustavia</i> Linnaeus (1775: 12), such as <i>G. angustifolia</i> Benth. (1845: 99), <i>G. occidentalis</i> Cuatrecasas (1951: 94), and <i>G. pubescens</i> Tafalla ex O. Berg (1856: 443, Cornejo 2018), and in two of the three valid species of <i>Couroupita</i> Aubl. (1775: 708): <i>C. guianensis</i> Aubl. (1775: 708) and <i>C. nicaraguarensis</i> DC. (1828: 294). Those rather inconspicuous blades margin colleters are minute, white, and secreting tiny microdroplets while functional in very young leaves, soon turning obsolete as persistent dark brown spaced marginal dots that can be observed in mature leaves under magnifying glass (10x); further field observations in remaining species of <i>Couroupita</i> and <i>Gustavia</i> may reveal that foliar marginal colleters might be also a trait at generic rank in the later genera. Leaf blade colleters reported in <i>Cariniana estrellensis</i> (Raddi) Kuntze (1898: 89) were suggested to provide young leaf protection (Souza Paiva 2012), so it is likely that a similar role could be played by the colleters from <i>Grias</i> and in the remaining species and genera of Lecythidaceae were they are found.</p> <p> <b>Etymology:</b> —The epithet honors José Portilla, who discovered the only population known, collected the type and made available to the author the specimens and field images of the new species.</p> <p> <b>Habitat and distribution:</b> — <i>Grias portillae</i> is an understory low tree that inhabits the interior of evergreen lower montane Andean slopes in wet forest at 1200 m. It is known only by the type locality in Río Cristal, at environs of Lita, province of Imbabura, northwestern Ecuador. Similar to <i>G. theobromicarpa</i>, another closely related species that is also endemic to evergreen montane Andean slopes in northwestern Ecuador, that was described based solely on the type, and from which two additional populations were discovered 10 years after the original publication, it is expected that further field exploration would yield the discovery of additional populations of <i>Grias portillae</i> in northwestern Ecuador.</p> <p> <b>Phenology:</b> —Flowering was observed in early July; fruiting material has not been collected yet.</p> <p> <b>Conservation status:</b> —This species is uncommon in Río Cristal, Lita, where less than 10 small trees have been found persisting in secondary habitats. Based on the very small area of occurrence (10 km 2), an extent of occurrence of 10.3 km 2, and its persistence in only one locality (fig. 1) that is under pressure by steady deforestation, forest fragmentation and conversion to pastures for livestock in northwestern Ecuador, <i>G. portillae</i> is here assigned a provisional category of Endangered (EN B2a(iv)), following the IUCN (2022) criteria.</p>Published as part of <i>Cornejo, Xavier, 2023, Grias portillae (Lecythidaceae): A new tree species from northwestern Ecuador, pp. 211-219 in Phytotaxa 625 (2)</i> on pages 212-216, DOI: 10.11646/phytotaxa.625.2.7, <a href="http://zenodo.org/record/10150802">http://zenodo.org/record/10150802</a>

Over 300 masl the habitats of Chongón-Colonche turn somewhat moister refreshed by winds and cooled by microdroplets of seasonal mist (Fig. 2: A; op. cit.). The new species is restricted to secondary and mostly conserved fragments of forests often with a closed canopy between 300 to 450 masl (Fig. 2: B); for 28 years has not been observed to colonize in full sun at open cut areas nearby (Cornejo, pers. obs. in the field). The relative age of those limestone rocky soils named as San Eduardo formation where <i>S. juradoi</i> occurs is Middle Eocene, Lutecian to Bartonian (47.8 to 37.8 MY), those soils contain macrofossils, calcareous algae, planktonic and benthic foraminifera (Moreira, 2019). The fossil evidence suggests that those soils were shallowly sumersed as a reef within an open marine environment, and that emerged as a consequence of a colission of coastal Ecuador against the western Andean margin most likely during or posteriorly to the latest Oligocene-Miocene (ca. 28.1 to 20.4 MY) (Jaillard <i>et al.</i> 1995). The new uplifted lands from Proto-Chongon-Colonche cordillera were islands that allowed the colonization most likely initially by mangrove trees that contributed at some extend on salt removal from new soils and simultaneously generating a top of organic ground, as they still do today just 3 to 5 km south from the type locality, forming new soils and subsequently allowing the settlement of terra firme species and ecosystems (Wolf 1892). It is here hypothesized that spatial isolation and environmental changes drove the process of plant speciation in Proto-Chongon-Colonche islands allowing the formation of the only known population of <i>S. juradoi</i>, and other local and regional endemics. The berries of <i>S. juradoi</i> are among the largest indehicent fleshy fruits of native species in the type locality, as trees as <i>Capparidastrum petiolare</i> (Kunth) Hutch. (Capparaceae), and <i>Gustavia angustifolia</i> Benth. (Lecythidaceae), and vines of <i>Curcurbita ecuadorensis</i> H.C. Cutler & Whitaker (Cucurbitaceae) (Belletini 2018, Cornejo obs. pers.), all of those relatively large-fruited species are dispersed by extant vertebrates and share a similar pattern of distribution that is endemic to the Pacific deciduous dry forests located in western Ecuador to northwestern Peru.</p> <p> <b>Phenology:</b> —Flowering from October through December, fruiting from late December through March.</p> <p> <b>Conservation status:</b> —The populations of <i>Salacia juradoi</i> occur within fragments of forests that encompasses an area of less than 75 km 2, that is ecologically isolated and restricted to the seasonally moister slopes and upper parts of Cerro Blanco which forms an interconnected continuum with Cerro Azul and the nearby Cerro 507, all covered by a Pacific dry deciduous seasonal native vegetation (Fig. 2). Those hills are private forests protected by the Cemento Nacional and ESPOL University that are under steady pressure by mining for cement and the expansion of urban frontier of the city of Guayaquil. Therefore, the preliminary status of EN B2 ab(iii) (IUCN 2017) is assigned to this new species.</p>Published as part of <i>Cornejo, Xavier & Lombardi, Julio A., 2021, Salacia juradoi (Celastraceae), a new species from coastal Ecuador, pp. 125-130 in Phytotaxa 524 (2)</i> on pages 128-129, DOI: 10.11646/phytotaxa.524.2.8, <a href="http://zenodo.org/record/5642118">http://zenodo.org/record/5642118</a>
La poursuite de la danseuse : Victor Manuel Llona, disparition d'un écrivain péruvien entre Charybde et Scylla
No full textInternational audienceLa persecución de la Dancing girl (the original title in French is La poursuite de la Dancing girl) is a short novel written by Peruvian Víctor Manuel Llona and published in French in La Nouvelle Revue Française, one of the most famous literary magazines of the first half of the twentieth century. It is a cosmopolitan tale, strange under the pen of a writer born in Lima, based between France and the United States. Before analyzing this work, which is about forty pages long and was published in two installments in 1913, Isabelle Tauzin-Castellanos introduces the author of this escapist tale in the style of Darío. The preliminary study precedes the novel published within the framework of the Cornejo Polar Center for Latin American Studies and the program On Disasters and Celebrations conducted by Daniel Carrillo Jara (North Texas University).La persecución de la Dancing girl (el título original en francés es La poursuite de la Dancing girl) es una novela breve escrita por el peruano Víctor Manuel Llona publicada en francés en La Nouvelle Revue Française, una de las más famosa revistas literarias del primer medio siglo XX.

La heterogeneidad cultural en la escritura de José Donoso en El obsceno pájaro de la noche: una respuesta a Antonio Cornejo Polar
No full textAntonio Cornejo Polar, in formulating the concepts of heterogeneous and homogeneous literature, exemplifies the latter with the work of José Donoso, thereby situating the author, his production, his referents, and the communicative circuit of his work within the same sociocultural universe. This paper aims to respond to Cornejo Polar's reading of Donoso's writing by proposing that, contrary to the Peruvian critic's assertion, there are elements that allow Donoso's narrative to be characterized as part of the so-called heterogeneous literatures. Within this framework, the analysis focuses on Donoso's novel The Obscene Bird of Night (1970) to identify the features that reveal the cultural heterogeneity present in the Chilean writer's work.Antonio Cornejo Polar, al plantear los conceptos de literatura heterogénea y literatura homogénea, ejemplifica esta última noción con la obra de José Donoso, de manera que sitúa al autor, su producción, su referente y el circuito de comunicación de su obra en un mismo universo sociocultural. Este artículo se propone responder a la lectura que Cornejo Polar realizó de la escritura de Donoso para postular que, contrario a lo que plantea el crítico peruano, existen elementos que permiten caracterizar la narrativa donosiana como parte de las llamadas literaturas heterogéneas. Dentro de este marco, el análisis se centra en la novela El obsceno pájaro de la noche (1970) de Donoso, a fin de establecer aquellos rasgos que dan cuenta de la heterogeneidad cultural presente en la producción del escritor chileno
Sentidos Subjetivos Sobre Profesionalismo de Docentes de Aula: Una Mirada Desde su Trabajo Cotidiano
No full textMagister en Psicología EducacionalDentro de un contexto de reformas globales educativas, marcadas por ideologías neoliberales y tecnologías manageriales, la docencia y su profesionalización ha sido un enfoque particularmente relevante durante las últimas décadas, particularmente en Latinoamérica. En Chile, las políticas de profesionalización y cursos de perfeccionamiento han sido rechazados o recibidos de manera ambigua por el profesorado, quedando éste al margen de un debate aún en curso tanto en las políticas educativas como en la investigación académica. Por lo tanto, la siguiente tesis apunta a recoger los sentidos que construyen docentes de aula sobre profesionalización, a partir de aspectos centrales de su trabajo cotidiano. La muestra consistió de dos docentes de diferentes establecimientos de la Región Metropolitana.
Los resultados muestran los sentidos particulares que construye cada docente sobre su ocupación, a partir de su experiencia histórica en la docencia, marcada por los desafíos y posibilidades que se encuentran día a día en la escuela. Asimismo, la identidad personal se relaciona de manera dialéctica e inseparable con la identidad ocupacional, donde las vidas personal y laboral se influencian mutuamente, dando cabida también a las propias convicciones dentro de su trabajo. Por otro lado, el profesionalismo como constructo no constituye un elemento central para la identidad de un docente, mientras que otra lo rechaza activamente en base a sus convicciones políticas. En conclusión, el debate político y académico en torno al profesionalismo y desarrollo profesional tiene el desafío de examinar con cautela la relevancia que tienen ambos conceptos dentro de la vida personal de docentes y su lugar en la práctica cotidiana; y abrirse a recoger la experiencia y reflexiones del profesorado en su conjunto dentro de los procesos de mejora de la práctica docent

El desarrollo capitalista latinoamericano en clave marxista
No full textEl presente capítulo ofrece una mirada desde la crítica marxiana de la economía política a los debates sobre las particularidades de las sociedades latinoamericanas. Más concretamente, tras un breve examen de los primeros intentos de dar cuenta de dicha especificidad en los estudios originados en la CEPAL y en el estructuralismo latinoamericano, el artículo pasa a focalizarse en la discusión crítica de las diferentes perspectivas que han tenido a estar asociadas a la llamada teoría de la dependencia (TD). Asimismo, y en base a las implicaciones de la discusión crítica de dicha tradición teórica, ofreceremos una perspectiva alternativa sobre la especificidad de las sociedades latinoamericanas.Fil: Starosta, Guido.

Taphonomy of the fossil record of macromammals of the Upper Pleistocene at level 4 of the Cueva de Prado Vargas (Cornejo, Burgos, Spain)
No full textLas técnicas de subsistencia en grupos humanos del pasado se investigan en profundidad a través del estudio de las acumulaciones fósiles, de su formación, origen y composición. Los conjuntos faunísticos localizados en los yacimientos arqueológicos pueden reflejar el tipo de estrategias desarrolladas por los homínidos a través de disciplinas como la Zooarqueología y la Tafonomía. El presente trabajo analiza el conjunto faunístico del Nivel 4 de la Cueva de Prado Vargas (Cornejo, Burgos, España) con una antigüedad de 46.400 años BP (MIS 3). Este yacimiento se ha interpretado como lugar de ocupación recurrente donde procesaron los recursos cárnicos los grupos neandertales que habitan la zona sur de la Cordillera Cantábrica, quienes intercalan su presencia con otros predadores que aprovechan su ausencia en la cavidad para dejar su huella en el registro.As predators, humans used to transport part of their prey to safe places like caves. Not only these accumulations, but also their formation, origin and composition constitute a fundamental basis to explore the behaviour of the human groups and their interaction with environment. Zooarchaeology and Taphonomy are complementary disciplines that allow us to approach these objectives. In this study, the faunistic assemblage of level 4 of Prado Vargas cave (Cornejo, Burgos, España) is analysed. This site is localised between the Cantabrian cornice and the north Meseta with a dating of 46.000 years BP. This work focuses on the livelihood strategies and Neanderthal behaviour, especially the way in which their prey was exploited. The analysis of the existing marks on the bones tells us about access to external tissues (meat, tendons or skin), processing and consumption, as well as bone for other non-nutritive purposes. They also allow us to explore and the way of access to animals, allowing us to distinguish the ways of life groups of prehistoric hunters-gatherers. Furthermore, we focus on differentiating the agent responsible for the fracture, as well as the state of the bone at the time that this occurred studying the patterns of fracturing and the marks associated with the percussion, as well as different tafonomic processes. We have collected a series of data that are offered in this work. The level 4 of Prado Vargas has been interpreted as a place of recurring habitat for Neanderthals, who intersperse their presence with other predators who take advantage of their absence in the cavity to leave their mark on the record.Este estudio recibe el apoyo de la Junta de Castilla y León desde la Consejería de Cultura y Turismo, Dirección General de Patrimonio Cultural, financiando el proyecto “Intervención arqueológica en la Cueva de Prado Vargas, en Cornejo (Merindad de Sotoscueva, Burgos) con número de expediente B2018/003394.
