Este artículo aborda la representación de las identidades LGBTIQ+ adolescentes en las dos primeras temporadas de la serie ‘Sex Education’ (Netflix, 2019-). Partiendo de una metodología de análisis anclada en la Teoría Queer y en el concepto de interseccionalidad se estudiará la construcción de aquellos personajes cuya expresión de género y/u orientación sexual trascienden los límites establecidos por la cisheteronormatividad, además de aquellos cuyos deseos (heterocoincidentes o no) no encajan dentro de lo que las sociedades occidentales entienden como «normal», puesto que se parte del rechazo a la norma como elemento constitutivo de lo queer. Los objetivos principales se concretan en: a.) determinar qué imágenes, conocimientos y construcciones epistemológicas se difunden en la serie en torno a la diversidad sexogenérica; y b.) definir qué discurso articula la serie sobre (no)identidades queer y la violencia que sufren las personas LGBTIQ+.

Primero se revisan algunos conceptos necesarios para la contextualización del trabajo. Después se analiza la historia de la Web, comenzando con Internet, y continuando con la World Wide Web, la Web Semántica, los problemas en Inteligencia Artificial, la Web 2.0, y Linked Data. Finalmente, se concluye el estudio con algunas aplicaciones de las tecnologías de la información para la Organización del Conocimiento en el campo bibliotecario, como FRBR, BIBFRAME e iniciativas de OCLC, así como algunos retos y oportunidades en los que la investigación y los expertos en Organización del Conocimiento podrían jugar un rol clave en relación con la Web Semántica. Palabras clave:Organización del conocimiento; tecnologías de la información; web semántica; inteligencia artificial; linked data. Challenges and opportunities for knowledge organization at the intersection with information technologiesAbstract: In this paper we study the intersection of Knowledge Organization with Information Technologies and the challenges and opportunities for Knowledge Organization experts that, in our view, are important to be studied and for them to be aware of. We start by giving some definitions necessary for providing the context for our work. Then we review the history of the Web, beginning with the Internet and continuing with the World Wide Web, the Semantic Web, problems of Artificial Intelligence, Web 2.0, and Linked Data. Finally, we conclude our paper with IT applications for Knowledge Organization in libraries, such as FRBR, BIBFRAME, and several OCLC initiatives, as well as with some of the challenges and opportunities in which Knowledge Organization experts and researchers might play a key role in relation to the Semantic Web.
Adriamycin-induced experimental esophageal atresia (EA) is often associated with malformations of neural crest (NC) origin, such as abnormal pharyngeal pouch derivatives like the thymus and the parathyroids. The aim of the present study was to examine whether NC-derived thyroid C-cells were abnormal in a rat model. Pregnant rats received intraperitoneally either 2 mg/kg Adriamycin (EA) or vehicle (controls) on days 8 and 9 of gestation. Fetuses were recovered on day 21, and blocks including the trachea and thyroid were fixed in formalin, coronally sectioned at 3-mum widths, and stained with standard hematoxylin and eosin until the largest area of thyroid was reached. From this point on, the 1st, 10th, and 20th slices were immunohistochemically stained with anti-calcitonin antibody. Positively-stained cells in each section of the gland were counted using a computer-assisted image analysis method, and the results were averaged. The distribution of the cells within the gland was assessed as well. Comparisons between EA and control rats were made by nonparametric tests with a significance threshold of p<0.05. The number of C-cells was dramatically reduced in EA animals compared with controls (32.4+/-36 vs. 92.3+/-60.5, p<0.001). Histology of the thyroid was similar in both groups, but the distribution of positive C-cells within the gland followed an abnormal pattern in EA rats. Adriamycin causes a pattern of NC-derived malformations, including a severe decrease in thyroid C-cells accompanied by abnormal distribution or migration patterns. These results represent further evidence of the involvement of NC organogenic control dysregulation in the pathogenesis of EA and its associated malformations. The similarities between the rat model and the clinical picture strongly support investigating other subclinical NC-derived anomalies in patients with EA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
