A performance como caminho pedagógico para a infância em con-dição vulnerável e migrante na escola

In this article, I’m going to present the partial results of an ongoing investigation that, from performative intersensibilities, focuses on the state of infancy as a condition of vulnerability that sets itself and the act of performance, as a teaching path of creation and investi-gation. As a result of said investigation, we are going to learn to inhabit the academy. Furthermore, we are going to deeply analyze the per-formative procedures that relapse on the healing pro-cess, all of this, through a genealogical and ethnographic exploration of my own experiences as an infant and as an investigator. In addition, I’m going to expand on how said performative procedures and methodologies have had an impact on my 20 years of experience as an art professor and on my current job as a principal of an educational institution. Finally, to this vulnerable condition that is the infancy, it is connected to the current problem of migration in our country, which forces us to take a step towards changing the course of action of the scholar field.Este artículo presenta los resultados parciales de una investigación en curso que, desde las intersensibilidades performativas, estudia la condición de infancia como condición de vulnerabilidad y que plantea la performance como ruta pedagógica de investigación-creación para aprender a habitar la escuela. A través de una exploración genealógica y autoetnográfica en torno a la experiencia de ser infante de la propia investigadora, se analiza el lugar de la performance en los procesos de reparación, y en cómo esta ha permeado las metodologías desarrolladas con niños y niñas, durante veinte años de trayectoria como docente de artes y actual administradora de una institución educativa de Bogotá. A esta condición de vulnerabilidad de infancia, en la que están presentes prácticas de violencia normalizadas, se suma el fenómeno de la migración que actualmente atraviesa el país y que demanda nuevas rutas de acción en el contexto escolar.Este artigo apresenta os resultados parciais de uma investigação em curso que, a partir das intersensibilida-des performativas, estuda a condição da infância como condição de vulnerabilidade e propõem a performance como um caminho pedagógico de Investigação- Criação para aprender a habitar a escola. Através de uma ex-ploração genealógica e auto etnográfica em torno da experiência do ser criança da própria investigadora, se analisa o lugar da performance nos processos de repa-ração e, como essa tem permeado as metodologias des-envolvidas com meninos e meninas, durante vinte anos de trajetória como docente de artes e como atual reitora de uma instituição educativa da cidade de Bogotá. A esta condição de vulnerabilidade da infância, na qual está presente práticas de violências normalizadas, se soma o fenômeno da migração que atualmente atravessa o país e que demanda novas rotas de ação no contexto escolar

Estrategias asociativas para las organizaciones solidarias en el marco del posconflicto en el Tolima

The peace process that has taken place in Colombia has encouraged the victims or victimizers of the armed conflict to see the creation of solidarity organizations as an alternative way of life. This generates an active participation in the business sector and in the labor market, where common benefits can be obtained, such as: improving the quality of life of the associates, reducing the inequality and poverty gaps caused by the conflict and contributing to the construction of peace territories. Therefore, it is important to design associative strategies that strengthen solidarity organizations that involve people involved in the armed conflict in order to generate a sustainable, lasting and competitive development in the market. This leads to the following specific objectives: (i) Carry out a diagnosis of the associativity processes of solidarity organizations in the post-conflict framework, (ii) Identify the main associative problems of the organizations, and (iii) Develop associativity strategies to boost the commercial development of their productive processes. Therefore, the methodology of this research is of a descriptive-propositive type, since it characterizes the internal processes carried out in solidarity organizations and proposes different associative strategies to promote commercial development and increase their business competitiveness.El proceso de paz que se ha llevado en Colombia ha impulsado que las víctimas o victimarios del conflicto armado vean la constitución de las organizaciones solidarias como una alternativa de vida. Ya que de esta manera se genera una activa participación en el sector empresarial y en el mercado laboral, donde se logra obtener beneficios comunes como: mejorar la calidad de vida de los asociados, la reducción de las brechas de la desigualdad y pobreza causadas por el conflicto y la contribución en la construcción de territorios de paz. Por consiguiente, nace la importancia de diseñar estrategias asociativas que fortalezcan a las organizaciones solidarias que involucran a personas pertenecientes en el conflicto armado para generar un desarrollo sostenible, perdurable y competitivo en el mercado. Lo que conlleva a plantear los siguientes objetivos específicos: (i) Realizar un diagnóstico los procesos de asociatividad de las organizaciones solidarias en el marco del posconflicto, (ii) Identificar las principales problemáticas asociativas de las organizaciones, y (iii) Elaborar estrategias de asociatividad para impulsar el desarrollo comercial de sus procesos productivos. Por tanto, la metodología de esta investigación es de tipo descriptivo - propositiva, ya que caracterizan los procesos internos que se llevan a cabo en las organizaciones solidarias y se proponen diversas estrategias asociativas para impulsar desarrollo comercial y aumentar su competitividad empresarial

Unveiling interactions mediated by B vitamins between diatoms and their associated bacteria from cocultures

Unveiling the interactions among phytoplankton and bacteria at the level of species requires axenic isolates to experimentally demonstrate their mutual effects. In this study, we describe the interactions among the diatoms Pseudo-nitzschia granii and Chaetoceros tenuissimus and their associated bacterial species, isolated from surface water of a coastal upwelling system using coculture experiments. Microalgae growth was assessed in axenic monocultures or in coculture with each of their co-isolated bacteria in the presence or absence of B vitamins. Pseudo-nitzschia granii growth was limited by B-vitamin supply, except when cultured with the bacteria Jannaschia cystaugens, which seemed to provide adequate levels of B vitamins to the diatom. Chaetoceros tenuissimus growth was reduced in the absence of B vitamins. Moreover, the growth of C. tenuissimus was stimulated by Alteromonas sp. and Celeribacter baekdonensis during the exponential growth. These results show a diversity of specific interactions between the diatoms and co-isolated bacteria, ranging from allelopathy to commensalism. Understanding how interactions between phytoplankton and bacteria modulate the structure and function of marine microbial plankton communities will contribute to a greater knowledge of plankton ecology and improve our ability to predict nutrient fluxes in marine ecosystems or the formation of blooms in a context of global change.Xunta de Galicia | Ref.

Structural changes during the natural aging process of InN quantum dots

The natural aging process of InN nanostructures by the formation of indium oxides is examined by transmission electron microscopy related techniques. Uncapped and GaN-capped InN quantum dots (QDs) on GaN/sapphire substrates were grown under the same conditions and kept at room temperature/pressure conditions. The GaN capping layer is found to preserve the InN QDs in the wurtzite phase, avoiding the formation of group-III oxides, while in the uncapped sample, a thin layer of cubic phases are formed that envelops the nucleus of wurtzite InN. These cubic phases are shown to be mainly bcc- In 2 O3 for long aged samples where the nitrogen atoms in the InN surface layers have been substituted by atmospheric oxygen. This process implies the gradual transformation of the In sublattice from hcp to a quasi-fcc structure. Metastable zinc-blende InN phases rich in oxygen atoms are proposed to act as intermediate phases and they are evinced in samples less aged. The large concurrence of interplanar spaces, the twin formation, and the existence of a free surface that facilitates the transformation support this mechanism and would explain the high instability of the InN nanostructures at ambient conditions.Comisión Interministerial de Ciencia y Tecnología (CICYT) MAT2007-60643Junta de Andalucía TEP383 EspañaUnión Europea NMP4-CT-2004- 50010

Spherical indentation of polycrystalline cubic boron nitride (PcBN): contact damage evolution with increasing load and microstructural effects

The extremely severe conditions at which cutting tools are exposed in hard machining operations require tool materials with outstanding mechanical properties. Excellent combinations of high hardness and fracture toughness are aimed to enhance wear and contact damage resistance; and thus, reliability of the tool. Here, spherical indentation is used to induce controlled damage, under monotonic loads, and to assess the resulting damage scenario of polycrystalline cubic boron nitride (PcBN). In doing so, two grades with different content of cBN particles as well as chemical nature of the binder are investigated. Systematic and detailed inspection of residual imprints, by means of optical and scanning electron microscopy, is conducted to document critical loads for damage emergence and evolution through different stages, as a function of increasing load and micro- structural assemblage. It is found that H-PcBN grade, with higher content of cBN particles and a metallic binder, exhibits higher resistance to crack nucleation as well as a more gradual transition between distinct damage scenarios. This enhanced response is linked to the concomitant increase of hardness and fracture toughness observed for that grade, as compared to the L-PcBN one, consisting of a significantly lower amount of superhard particles bound by a binder of ceramic nature. In-depth inspection of interaction between fissures and micro- structure indicates the existence of four different crack paths for both PcBN grades - transgranular through cBN particles, across the binder phase, and intergranular along either cBN/cBN or cBN/binder interfaces. Relative frequency of these crack paths as well as operative toughening mechanisms define the effective crack growth resistance of each PcBN grade. In this regard, a higher fracture toughness is assessed for H-PcBN, as a result of crack bridging by metallic ductile ligaments together with the effective barrier-like role played by substructural features within cBN particles. Meanwhile, L-PcBN grade shows a rather low crack growth resistance, in direct correlation with the intrinsic brittle nature of the contiguous ceramic binder through which crack extension predominantly takes place. These relative differences in resistance to crack nucleation and growth become key for understanding the enhanced contact damage behaviour determined for the grade with higher content of cBN particles in this study.Peer ReviewedPostprint (published version
