General morphology and updated taxonomy of the genus Aporcelinus Andrassy, 2009 (Dorylaimida: Aporcelaimidae)
No full textThis paper deals with the general morphology of the dorylaimid genus Aporcelinus as a basis for updating its taxonomy. This taxon is morphologically rather homogeneous and characterised by a peculiar combination of apomorphic states of several features, which are described, illustrated and discussed, particularly those concerning lip region, odontostyle, pharyngo-intestinal junction, female genital tract, and caudal region. A revised generic diagnosis is presented and the separation of the genus from its relatives analysed. The updated inventory of Aporcelinus includes 29 valid species with their synonyms and two species inquirendae. A key to identification of species is also given, and a compendium of their morphometrics is provided for comparative purposes

No full textDescription of Aphelenchoides giblindavisi n. sp. (Nematoda: Aphelenchoididae), and Proposal for a New Combination
No full textOne new and one known species of the genus Aphelenchoides from Iran are studied. Aphelenchoides giblindavisi n. sp. is mainly characterized by having five lines in the lateral fields at mid-body, and a single mucro with several tiny nodular protuberances, giving a warty appearance to it, as revealed by detailed scanning electron microscopic (SEM) studies. The new species is further characterized by having a body length of 546 to 795 mu m in females and 523 to 679 mu m in males, rounded lip region separated from the rest body by a shallow depression, 10 to 11 mu m long stylet with small basal swellings, its conus shorter than the shaft (m = 36-43), 52 to 69 mu m long postvulval uterine sac (PUS), males with 16 to 18 mu m long arcuate spicules, and three pairs of caudal papillae. The new species was morphologically compared with two species of the genus having five lines in the lateral fields namely A. paramonovi and A. shamimi and species having a warty-surfaced mucro at tail end and similar morphometric data ranges. The morphological features and morphometrics of the second studied species, A. helicus, agreed well with the data given for the type population. However, detailed study of fresh females revealed it has three drop-shaped stylet knobs and long PUS, making it typologically similar to the genus Robustodorus, meriting its taxonomic revision, i.e., transferring to it. In molecular phylogenetic analyses using partial small and large subunit ribosomal RNA gene (SSU and LSU rDNA) sequences, the new species formed a Glade with A. heidelbergi in both SSU and LSU D2-D3 trees. The species A. helicus, however, clustered inside a well-supported Glade of the genus Robustodorus in both trees, corroborating its newly proposed taxonomic placement as Robustodorus helicus n. comb
Human trafficking
No full textEl presente trabajo aborda la definición del execrable problema de la trata de seres humanos. Comienza con el análisis del concepto de trata de seres humanos y sus elementos a través de la normativa internacional y europea del siglo XXI. A continuación, aborda las similitudes, diferencias y conexiones con el tráfico de personas. Además, se revisan los problemas para su medición y los datos que, en diversos ámbitos, se manejan para observar su evolución. Por último, se apuntan los cambios y retos que la era digital, y, también, la pandemia de COVID-19 plantean a la respuesta y lucha contra la trata de seres humanos.
Abstract: This paper addresses the definition of the heinous problem of trafficking in human beings. It starts with an analysis of the concept of trafficking in human beings and its elements through 21st century international and European regulations. It then discusses the similarities, differences, and connections with human trafficking. In addition, it reviews the problems of measurement and the data that are used in various fields to observe its evolution. Finally, it points out the changes and challenges that the digital era, and also the COVID-19 pandemic, pose to the response and fight against human trafficking
A new user-adapted search haptic algorithm to navigate along filiform structures
No full textOne of the mayor research challenges of this century is the understanding of the human brain. Regarding this field line, simulation based research is gaining importance. A large amount of money is being spent in huge international projects such as The Human Brain Project [1] and The Blue Brain [2]. The behavior of the brain and, therefore, the behavior of brain simulations depend to a large extend on the neural topology. Neural elements are organized in a connected, dense, complex network of thread-like (i.e., filiform) structures. The analysis of a computer-based simulation using just the visual modality is a highly complex task due to the complexity of the neural topology and the large amounts of multi-variable and multi-modal data generated by computer simulations. In this paper, we propose the use of haptic devices to aid in the navigation along these neural structures, helping neurobiologists in the analysis of neural network topologies. However, haptic navigation constrained to complex filiform networks entails problems when these structures have high frequency features, noise and/or complex branching nodes. We address these issues by presenting a new user-adapted search haptic method that uses the forces exerted by the users to infer their intentions. In addition, we propose a specific calibration technique to adapt the haptic navigation to the user's skills and to the data. We validate this approach through a perceptual study. Finally, we show in this paper the application of our method to the analysis of dense and complex filiform structures in the neurobiology context. Additionally, our technique could be applied to other problems such as electronic circuits and graph exploration. © 2014 IEEE
Las DAOs y el reto de controlar al algoritmo
No full textLas DAO -organizaciones autónomas descentralizadas- son estructuras de gobierno que asistidas de las tecnologías de Blockchain, Inteligencia Artificial y otras herramientas digitales consiguen el propósito de adoptar decisiones y coordinar actividades para el impulso de una finalidad que une a una comunidad, incluso aquellas que se dedican al ámbito financiero. La obra afronta la descripción del fenómeno, subrayando las fortalezas y debilidades de su funcionamiento. En particular detalla los singulares conflictos de interés y riesgos que les afectan. Es objeto del contenido analizar el procedimiento de constitución y la forma de configurar sus recursos y capacidades para el autogobierno de la estructura. Sus los rasgos disruptivos junto a la nota de la universalidad dificultan el encaje legal. El estudio de una DAO en el entorno de las finanzas Defi ilustra un particular caso de uso
Propuesta educativa sobre la responsabilidad social universitaria y los objetivos de desarrollo sostenible: potenciando la alfabetización mediática a través del podcast
No full textEn la era digital, los podcasts se han convertido en una herramienta educativa innovadora
y accesible. La presente propuesta formativa se basa en el desarrollo de podcasts con una estructura de reportaje
radiofónico de 20 minutos de duración sobre cada uno de los Objetivos de Desarrollo Sostenibles (ODS) propuestos
por la Organización de las Naciones Unidas. Esta propuesta está destinada a los alumnos del tercer curso del
doble grado universitario de Comunicación Audiovisual y Periodismo para la asignatura Producción de Programas
Informativos en Radio de la Universidad Rey Juan Carlos, pero es fácilmente adaptable a otras asignaturas de dichos
grados o bien, a otros grados. Profundizando un poco más en la universidad elegida, se indica que la Estructura del
Proyecto URJC 2030 resalta su compromiso con los Objetivos de Desarrollo Sostenible (ODS), puesto que aspira
a ser un referente internacional como Universidad 2030, uniendo los esfuerzos de toda la comunidad universitaria
(alumnos, docentes y personal de servicios y administración) en torno a los 17 ODS
