Attitudes of Children with Autism towards Robots: An Exploratory Study

In this exploratory study we assessed how attitudes of children with autism spectrum disorder (ASD) towards robots together with children's autism-related social impairments are linked to indicators of children's preference of an interaction with a robot over an interaction with a person. We found that children with ASD have overall positive attitudes towards robots and that they often prefer interacting with a robot than with a person. Several of children's attitudes were linked to children's longer gazes towards a robot compared to a person. Autism-related social impairments were linked to more repetitive and stereotyped behaviors and to a shorter gaze duration in the interaction with the robot compared to the person. These preliminary results contribute to better understand factors that might help determine sub-groups of children with ASD for whom robots could be particularly useful.Comment: Presented at Interaction Design and Children (IDC-CRI2018) Workshop (arXiv:submit/2277826

Tipificación de Opuntia australis (Cactaceae) con una lámina original de 1882 e historia del hallazgo de la planta

The neotypification of Opuntia australis F.A.C.Weber, basionym of Pterocactus australis (F.A.C.Weber) Backeb., is made here thanks to the discovery of Weber?s personal notes about it, and of two notebooks containing respectively a drawing and a short description of that plant, both made at the time of its first collection in 1882. Outlined as well is the poorly documented scientific expedition that made this first discovery and the cultivation of an early plant by F.E. Schlumberger on Weber?s behalf. A Weber?s note confirms he knew the mentioned illustration. A herbarium specimen from the same gathering has been found, but it cannot be considered original material since there is no evidence that it was seen by Weber. However, this specimen is here designated as epitype.Se realiza la neotipificación de Opuntia australis F.A.C.Weber (basónimo de Pterocactus australis (F.A.C.Weber) Backeb.), gracias al hallazgo de manuscritos sobre esta especie de su autor y de una libreta con un dibujo a color del taxón, efectuado al tiempo de su primera colección. También se menciona una segunda libreta, complementaria, con una breve descripción de la planta y la expedición científica -poco documentada- que realizó el hallazgo en 1882, y a F. E. Schlumberger, quien la cultivó, colaborando con el autor. Una nota de Weber confirma que conoció la ilustración mencionada. Además, se encontró un ejemplar de herbario de la misma colección, que si bien no puede ser considerado material original ya que no consta que haya sido visto por el autor, es designado como epitipo.Fil: Kiesling, Roberto.

Frédéric Albert Constantin Weber Travaux consacrés aux Cactus et Agaves II: Notes de travail - Correspondance diverse - Travaux annexes

Ce Volume 2 est consacré à de nombreux documents personnels de Weber. Une biographie de Weber devait clore ce volume, mais nous n’avons pas pu nous accorder sur son organisation et son contenu. Elle sera probablement publiée plus tard sous l’autorité de Jean-René Catrix seul qui en était l’artisan. Le travail a débuté en 2018 et devait être finalisé début 2020. Mais l’épidémie de covid-19 en a décidé autrement. La conception et la réalisation de ce volume 2 s’en sont ressenties, mais juillet 2020 a marqué la finalisation. Les documents personnels de Weber ont été retrouvés au Muséum national d’histoire naturelle à Paris (MNHN), où ils peuvent être consultés sur demande préalable1 dans la « salle de réserve ». Ces documents résultent, en totalité ou en partie, d’une donation faite par le fils de Weber et probablement par Robert Roland-Gosselin. Ce sont des notes de travail de Weber, des planches d’herbier et de la correspondance avec divers botanistes ou amateurs français et étrangers. Il est toutefois certain qu’une part des documents a été dispersée ou « rangée ailleurs », voire « définitivement empruntée ». En effet, aucune des photographies mentionnées dans la correspondance n’a été retrouvée, certaines chemises sont vides, la correspondance avec Schickendantz, Spegazzini ou Schumann est très réduite ou inexistante.Fil: Catrix, Jean René.

Epidemiology of athletic injuries in classic ballet practitioners

Specific overloads of ballet practice may represent risk factors for injuries. The objective of this study was to analyze the epidemiology of typical injuries of ballet, including factors associated with history of injury in ballet practitioners. Studied subjects integrated 124 dancers, of both genders, from nine ballet schools from Campo Grande, Mato Grosso do Sul State, Brazil. To obtain information about injuries, we used a morbidity survey. Participants were divided into two groups: G1 (with injuries) and G2 (without injuries). In relation to prevalence of injuries, 89 cases were registered, and 61 dancers (49%) reported damages incidence, with record of 1.48 cases per practitioner. Moreover, the G2 presented higher body weight (G1: 51±8 versus G2: 55±10 kg) and training time (G1: 4.0±2.0 versus G2: 5.0±4.1 years). With respect to injury type, joints (32%) and muscle affections (25%) were the main occurrences in the lower limbs (85%) due to specific exercises (30%). Weekly exposure time was the most important mechanism to injury installation. The more important causal circumstance to injury occurrence was constituted by specific training (49%) and choreographic performance (41%). In conclusion, evidences have showed that joint injuries in lower limbs are the main classical ballet injuries in ballet practitioners, and weekly exposure time is the most important factor associated with injuries in classical ballet.Demandas específicas da prática de ballet podem representar fatores de risco para lesões musculoesqueléticas. Este estudo teve por objetivo analisar a epidemiologia das lesões típicas do ballet, com fatores associados ao histórico de lesão em bailarinos. A casuística integrou 124 participantes de ambos os sexos, procedentes de nove escolas e companhias de ballet de Campo Grande, no Mato Grosso do Sul. Para registro de lesões, utilizou-se um inquérito de morbidade referida. Os participantes foram distribuídos em dois grupos: G1, sem lesão, e G2, com lesão. Em relação à presença de lesão, foram registrados 89 casos, sendo que 61 bailarinos (49%) relataram terem se lesionado, com registro de 1,48 casos por praticante. O G2 apresentou maior massa corporal (G1: 51±8 versus G2: 55±10 kg) e tempo de treinamento (G1: 4,0±2,0 versus G2: 5,0±4,1 anos). Houve predomínio de lesões articulares (32%) e musculares (25%) nos membros inferiores (85%), decorrentes de exercícios específicos (30%). O maior tempo semanal de prática configurou o principal fator de risco para lesão. A circunstância que mais provocou lesões foi o treino específico (49%), seguido pelo ensaio de coreografia (41%). Conclui-se que as lesões articulares em membros inferiores são as principais lesões do ballet clássico, e o tempo semanal de exposição constitui o principal fator associado a lesões no ballet clássico.Demandas específicas de la práctica de balé pueden representar factores de riesgo para lesiones musculoesqueleticas.

El G2 presentó mayor masa corporal (G1: 51±8 versus G2: 55±10 kg) y tiempo de entrenamiento (G1: 4,0±2,0 versus G2: 5,0±4,1 años). Hubo predominancia de lesiones articulares (32%) y musculares (25%) en las extremidades inferiores (85%) originarias de ejercicios específicos (30%). El mayor tiempo semanal de práctica se configuró como el principal factor de riesgo para lesión. La circunstancia que más causó lesiones fue el entrenamiento específico (49%), seguido por el ensayo de coreografía (41%). Se concluso que las lesiones articulares en extremidades inferiores son las principales lesiones del balé clásico, y el tiempo semanal de exposición se constituye el principal factor asociado a las lesiones en el balé clásico

Cell culture and variations in the comet assay do not affect the genomic integrity of adipose-derived stem cells

The application of quality control tests, such as the comet assay, are essential when adipose-derived stem cells are cultured for therapeutic purposes. However, the steps involved in the development of this assay should be investigated, in order to reduce their influence on genomic damage in cells. The study aimed to evaluate if the cell culture process causes DNA damage, and if variations in the lysis time and pH of the electrophoresis buffer interfere in the genotoxicity results. Four different comet assay protocols were evaluated, and the effects of lysis time and pH conditions of the electrophoresis buffer solution were stated as follows: 2 hours and pH 12; 24 hours and pH 12; 2 hours and pH ≥ 13 and 24 hours and pH ≥ 13. The tail moment was analyzed, and results indicated that at the time cells were detached from the flasks, there was little damage to the DNA in the adipose-derived stem cells, which was confirmed by evaluation of the expression of mRNA genes involved in damage and repair processes of genetic material. Also, the tail moment values ​​did not show significant differences among the four evaluated protocols (p < 0.05), with no indication of damage when compared to the positive control (p < 0.05). Thus, any of the tested protocols can be applied in genotoxicity tests with adipose-derived stem cells, without causing damage to them
