Characterisation of single semiconductor nanowires by non-destructive spectroscopies
2015
Los nanohilos semiconductores (NWs, de su nombre inglés, nanowires) tienen una amplia gama de aplicaciones en el campo de la optoelectrónica (emisores de luz y diodos láser), nano-electrónica (circuitos lógicos y transistores de efecto de campo), y detección y producción de energía (células solares). En términos generales, los NWs pueden ser descritos como nanoestructuras de forma alargada con diámetros que van típicamente de decenas a cientos de nanómetros, y con longitudes que oscilan desde pocas hasta las decenas de micras. Dicha morfología ofrece dos ventajas principales en comparación con las capas: su alta relación superficie-volumen y su mayor calidad cristalina, ambas beneficiosas p…
El TDHA a través de narraciones ilustradas
2018
A través de esta propuesta pretendemos contribuir a la atención educativa de los alumnos de Educación Infantil que muestran un patrón conductual compatible con el diagnóstico del trastorno por déficit de atención con hiperactividad (TDAH), desde un enfoque preventivo, estimulando el análisis y la reflexión sobre determinados comportamientos mediante el género narrativo, por su valor educativo en esta etapa. Los alumnos de Educación Infantil se encuentran en un momento madurativo de fascinación natural hacia la escucha de narraciones. Presentamos una propuesta basada en narraciones ilustradas, ideadas y elaboradas por alumnos del Grado en Educación Infantil de la Universidad CEU Cardenal Her…
Análisis de la narrativa infantil escrita por mujeres (1920-1939)
2012
Resumen basado en el de la publicación Título, resumen, palabras clave en español e ingles Se aborda el estudio de un corpus de cuentos infantiles publicados por mujeres en la prensa nacional de adultos entre 1920 y 1939. Son sus objetivos : hacer visible esa producción ; analizar las diferentes propuestas estéticas e ideológicas formalizadas en esta escritura y reinsertar esta producción artística en el sistema literario en el que se produjo, ya que nace dentro de éste y son las circunstancias históricas posteriores las que lo aíslan y lo convierten en una escritura menor. La visibilización de la escritura femenina infantil para niños se constituye en tres fases : autoras que publican en e…
Communicative skills in Spanish children with Autism Spectrum Disorder and children with Attention Deficit Hyperactivity Disorder. Analysis through p…
2018
Background Communicative skills are one of the main deficits experienced by children with Autism Spectrum Disorder (ASD). The differential diagnosis is a complex issue that clinicians often face. For this reason, this study has two objectives: 1) to analyze the similarities and differences that children with Attention Deficit Hyperactivity Disorder (ADHD) and children with ASD present in their linguistic and communicative skills, through parentś perceptions and narrative production; 2) to identify the relative importance of the skills analyzed in discriminating children with ASD versus children with ADHD, as well as the classification power of each of the two measurement methods used. Metho…
Narratives of children with high-functioning autism spectrum disorder: A meta-analysis
2016
Abstract Background The aim of this meta-analysis was to analyze the narrative performance of children and adolescents with high-functioning Autism Spectrum Disorders (ASD) in terms of microstructure, macrostructure and internal state language. Method A systematic literature search yielded 24 studies that met the predetermined inclusion criteria. Effect sizes for each study were calculated for eight variables and analyzed using a random effects model. Intellectual ability, age and type of narrative were considered as potential moderators. Results Results revealed that the children with ASD performed significantly worse than their peers on all the variables considered. Conclusions Findings a…
Tumours of Nasal Septum: A Retrospective Study of 32 Patients
2022
Objective: Tumours of the nasal septum are a rare and heterogeneous group of lesions in the sinonasal tract. The management of the different lesions of this site is debated. The aim of this study is to share our experience on a rare clinical condition and stimulate other centres to publish theirs. Methods: We retrospectively analysed the databases of sinonasal tumours treated at the Sections of Otolaryngology (ENT) of two University Hospitals (Palermo and Genova) between 2012 and 2020. Results: From the two databases, a cohort of 32 patients with tumours of nasal septum were selected. All patients underwent an endoscopic examination. Large tumours underwent preoperative computed tomography …
Tensions on Finnish Constitutional Bilingualism in Neo-nationalist Times : Constructions of Swedish in Monolingual and Bilingual Contexts
2020
This chapter analyses the tensions on the status of Finnish constitutional bilingualism from the perspective of higher education, more precisely from the position of Swedish in one monolingually Swedish university (Åbo Akademi University [ÅAU]) and one bilingual university (University of Helsinki [UH]). It contributes to an understanding of the position of minority languages in universities in times when the use of English has increased on one hand and neo-nationalist tendencies stressing the importance of national language(s) are on the rise on the other. Apparently, the new bilingual programmes at UH challenge the tradition of institutional separation of national languages. At ÅAU, in tur…
“KKona where’s your sense of patriotism?” : Positioning Nationality in the Spectatorship of Competitive Overwatch Play
2022
AbstractThis chapter analyzes the discursive construction of nationality and ethnicity in the context of the Overwatch World Cup 2019 and especially among the discussions of the world cup’s spectators on the live-streaming platform Twitch. Drawing on the positioning theory and the concept of banal nationalism, our study demonstrates how esports fans are active negotiators and co-creators of the esports discourse. The analysis illustrates what kind of role nationality and ethnicity take in this environment, in other words what they come to mean for those participating in the discourses defining them.
Elemental and microbiota content in indoor and outdoor air using recuperation unit filters
2021
Detection and quantification of engineered nanomaterials in environmental systems require precise knowledge of the elemental composition, association, and ratios in homologous natural nanomaterials (NNMs). Here, we characterized soil NNMs at the single particle level using single particle-inductively coupled plasma-time of flight-mass spectrometer (SP-ICP-TOF-MS) in order to identify the elemental purity, composition, associations, and ratios within NNMs. Elements naturally present as a major constituent in NNMs such as Ti, and Fe occurred predominantly as pure/single metals, whereas elements naturally present at trace levels in NNMs occurred predominantly as impure/multi-metal NNMs such as…
