THE CORSET AND THE HIJAB: THE DISCURSIVISATION OF IDENTITY BETWEEN THE WEST AND THE ORIENT
The present thesis contains the commentary reviewing nine publications produced and submitted between 2016 and 2020. The portfolio debates the intersection of Communication and Semiotics theories, utilised in the study of Fashion and the Body as media displaying multifarious relations of communication which, through their iterations in culture, generate the interactions between human subjects, which are the foundation of the social milieu. Throughout the sections, the matter is explored in the proposition of a method to the study of rhythmic changes and their alternation, which is employed in a series of analyses addressing Western dress and the hijab, to then unfold into the works’ core contribution: the postulation of the West and the Orient in parallel, rather than viewed as opposed cultural practices. Utilising mainly the Semiotic and Socio-semiotic Theories developed by Greimas (1970, 1983, 1984, 1986, 1987, 2000; Greimas & Courtés, 1993) and Landowski (1992, 1997, 2004, 2005, 2009, 2010,2014, 2017) as a foundation to the construction of our methodology (Jardim, 2021c), the work merges Post-colonial Theory (Ahmed, 2006; Bhabha, 1994; Buruma & Margalit, 2004; Lévi-Strauss, 1952; Said, 2003; Spivak, 1999), and works about the corset (Jardim, 2014; Kunzle, 2004; Steele, 1997, 2001) and the hijab (Ahmed, 2011; El Guindi, 1999; Shirazi, 2003) to promote an examination of the objects as communication praxes constructing and disseminating ideas linked to the role of women, as well as discourses about Culture, Identity, and Religion. The investigation results in questioning multiple relations of power articulated through various media of communication—the verbal use of language and the discourses it creates but, equally, the visual dimension of the body, dress, and the imagery constructed around them— rejecting the dogmatic binaries which form our current worldview to, instead, observe the semio-narrative structures of discourses and practises which reveal the entanglement of Western and Oriental dress practices

Physical properties of single-crystalline fibers of the colossal-magnetoresistance manganite La0.7Ca0.3MnO3
We have grown high-quality single crystals of the colossal-magnetoresistance
(CMR) material La0.7Ca0.3MnO3 by using the laser heated pedestal growth (LHPG)
method. Samples were grown as fibers of different diameters, and with lengths
of the order of centimeters. Their composition and structure were verified
through X-ray diffraction, scanning electron microcopy with EDX (Energy
Dispersive X-ray Analysis) and by Rietveld analysis. The quality of the
crystalline fibers was confirmed by Laue and EBSD (Electron Backscatter
Diffraction) patterns. Rocking curves performed along the fiber axis revealed a
half-height width of 0.073 degrees. The CMR behavior was confirmed by
electrical resistivity and magnetization measurements as a function of
temperature.Comment: 11 pages (including 3 figures); to appear in Appl. Phys. Let
Amostragem para diagnose do estado nutricional e avaliação da fertilidade do solo em caramboleiras.
Para a realização de uma análise confiável, a etapa mais sensÃvel e que merece extremo cuidado é a amostragem do tecido vegetal e do solo. A amostra mais adequada é aquela que representa o melhor possÃvel a área de estudo, exigindo um mÃnimo de plantas amostradas para atender a esse objetivo e com o menor número possÃvel de amostras simples coletadas. Assim, o presente trabalho procurou dimensionar o número de plantas a serem amostradas para a diagnose do estado nutricional, bem como o número de amostras simples necessárias para formar a amostra composta, para fins de avaliação da fertilidade do solo cultivado com caramboleiras. O estudo foi realizado em um pomar comercial de caramboleiras, no municÃpio de Vista Alegre do Alto (SP), empregando-se amostragem aleatória, coletando-se a sexta folha a partir do ápice do ramo da caramboleira, na altura mediana da frutÃfera, no florescimento da cultura, em 40 plantas. Foram coletadas, também, 30 amostras simples de solo, em zigue-zague, nas linhas da cultura, com o auxÃlio de um trado tipo holandês, nas camadas de 0 a 0,2 m e 0,2 a 0,4 m. Considerando-se aceitável um erro amostral de 10%, 21 plantas de carambola seriam suficientes para as determinações quÃmicas foliares de macronutrientes. Já para os micronutrientes, seriam necessárias, no mÃnimo, 52 plantas amostradas. O aumento do número de amostras simples reduziu o erro porcentual na estimativa da média desejada, permitindo a recomendação de 14 e 17 amostras simples nas camadas de 0 a 0,2 m e 0,2 a 0,4 m (erro = 20%), respectivamente. Sampling for diagnosis of nutritional status and assessment of fertility in starfruit orchards. Abstract: For a reliable nutritional analysis, the most sensitive stage is the plant and soil samplings. The most proper sampling is the one that best represents the area under study, requiring a minimum of sampled plants and the least possible number of simple samples collected. This work aimed to assess the number of plants to be sampled for the diagnosis of nutritional status, as well as the number of simple samples for making up of the compost sample for evaluating the soil fertility in starfruit orchard. This study was performed in a commercial starfruit orchard, in Vista Alegre do Alto, State of São Paulo. Random sampling was taken, collecting the sixth leaf from the apex of the branch of 40 starfruit trees, at the medium canopy height during blooming season. In the same way, 30 simple soil samples were collected, in a zigzag pattern following the planting lines, using a Dutch-type auger, at depths of 0 to 0.2 m and 0.2 to 0.4 m. Assuming a sample error of 10%, 21 starfruit trees would be sufficient for determining the chemical leaf macronutrients. For micronutrients, a minimum of 52 sampled plants would be necessary. Increasing the number of soil samples resulted in reduced percentage of error within the desired average estimate, thus allowing for a recommendation of 14 to 17 simple samples at depths of 0 to 0.2 m and 0.2 to 0.4 m (error = 20%), respectivel
Alcances y limitaciones actuales de la actividad experimental en escuelas de Enseñanza Media de la provincia Santiago de Cuba: criterios de alumnos y profesores
El propósito de este estudio es explorar el estado actual de desarrollo de las actividades experimentales en la asignatura de FÃsica en escuelas de Enseñanza Media de la provincia de Santiago de Cuba ya que constituye un aspecto medular en la construcción del conocimiento cientÃfico. Para la recogida de la información se utilizaron dos instrumentos: una encuesta y una entrevista que fueron aplicadas a 268 alumnos y 18 profesores de cinco escuelas con entornos socioculturales diferentes. Los datos obtenidos de las encuestas de ambos sujetos están referidos a: la existencia o no de infraestructura de laboratorio en las escuelas, las caracterÃsticas de sus participaciones en los laboratorios y la frecuencia de realización de los mismos. Complementan esta información sus opiniones expresadas en las respuestas a las entrevistas, donde se destaca el papel que atribuyen a los experimentos en el proceso de enseñanza-aprendizaje. Los resultados indican un incremento en la motivación y en la asimilación de los contenidos por parte de los alumnos que participaron en las demostraciones experimentales en las escuelas con infraestructura de laboratorio. Se manifiestan también limitaciones en el orden material con énfasis en las escuelas más alejadas del centro de la ciudad de Santiago de Cuba y de preparación de los profesores para una eficiente utilización del instrumental que poseen en función de la docencia.The purpose of this study is to explore the current developmental status of experimental activities within the subject of physics in Middle Schools in the Santiago de Cuba Province, which constitutes a key aspect in the attainment of scientific knowledge. Two different tools were used in the information gathering process: one poll and a series of iinterviews involving 268 students and 18 professors from five schools of diverse socio-cultural environments. The resulting data relates to: the availability - or not - of lab infrastructure at schools; the type of lab participation; and its frequency. This information is complemented by the opinions expressed in the responses to the interviews where the role attributed to experimental activity in the teaching-learning process is highlighted. The results show an increment in motivation and subject learning on the part of the students when they have access to experimental demonstrations at schools with lab infrastructure. Other limitations observed, especially at schools further away from Santiago de Cuba, were related to the lack of material resources and the preparation of teachers in relation to their utilization of available resources in the teaching function.CAPES/MES (109/10
Out of Africa: the mite community (Arachnida: Acariformes) of the common waxbill, Estrilda astrild (Linnaeus, 1758) (Passeriformes: Estrildidae) in Brazil
Abstract
Background
The common waxbill, Estrilda astrild (L., 1758) (Passeriformes: Estrildidae) is a small passerine bird native to Sub-Saharan Africa that has been introduced into several regions of the world.
Results
In the present paper, eight mite species (Acariformes) are reported from this host from Brazil, including three species new to science: Montesauria caravela n. sp., M. conquistador n. sp. (Proctophyllodidae), Trouessartia transatlantica n. sp., T. minuscula Gaud & Mouchet, 1958, T. estrildae Gaud & Mouchet, 1958 (Trouessartiidae), Onychalges pachyspathus Gaud, 1968 (Pyroglyphidae), Paddacoptes paddae (Fain, 1964) (Dermationidae) and Neocheyletiella megaphallos (Lawrence, 1959) (Cheyletidae). Comparative material from Africa was also studied.
Conclusions
These mites represent at least three morpho-ecological groups regarding their microhabitats occupied on the bird: (i) vane mites (Montesauria and Trouessartia on the large wing and tail feathers); (ii) down mites (Onychalges); and (iii) skin mites (Paddacoptes and Neocheyletiella). On one bird individual we found representatives of all eight mite species. Although the common waxbill was introduced to the Neotropical region almost two centuries ago, we demonstrate that it still retains its Old World acarofauna and has not yet acquired any representatives of typical Neotropical mite taxa.https://deepblue.lib.umich.edu/bitstream/2027.42/137645/1/13071_2017_Article_2230.pd
