Pakārtojuma palīgteikumu lietojums laikrakstā The Irish Times
2017
Sintakse un pakārtojuma palīgteikumi ir pētīti dažādos diskursos, taču ir veikti tikai pāris pētījumi šajā jomā laikrakstā The Irish Times. Tāpēc šī pētījuma mērķis bija analizēt pakārtojuma palīgteikumu minētajā laikrakstā, noteikt to visbiežāk sastopamo atrašanās pozīciju teikumā un noskaidrot kādi pakārtojuma palīgteikumu veidi ir atrodami iepriekšminētajā laikrakstā. Šī pētījuma rezultāti atklāj, ka lielākajā daļā gadījumu pakārtojuma palīgteikumi atradās teikuma vidū vai beigās, taču tika atklāti tikai daži gadījumi, kad pakārtojuma palīgteikums atradās teikuma sākumā. Turklāt, vislielākais skaits piemēru finīta formā bija apzīmējoši, lai gan apstākļa pakārtojuma palīgteikumi finīta fo…
Clinical evaluation of automated capillary refill time estimation in dogs and cats
2019
In this study, we clinically evaluated a pulse oximeter-based device for automated capillary refill time (CRT) estimation in dogs and cats. CRT can reveal conditions like shock or anemia in dogs and cats. However, visual CRT estimation has low repeatability, and the available optical systems for automated estimation are not suitable for pets. We evaluated a custom-made portable CRT measuring device on various measurement sites of 12 dogs and 11 cats with parallel visual CRT estimation on the gum by treating veterinarian. The capillary refill was also recorded by a video camera for reference. The visual and video procedures were moderately correlated with the coefficient of 0.61; visual CRT …
Nonlinear Time-Series Adaptation for Land Cover Classification
2017
Automatic land cover classification from satellite image time series is of paramount relevance to assess vegetation and crop status, with important implications in agriculture, biofuels, and food. However, due to the high cost and human resources needed to characterize and classify land cover through field campaigns, a recurrent limiting factor is the lack of available labeled data. On top of this, the biophysical–geophysical variables exhibit particular temporal structures that need to be exploited. Land cover classification based on image time series is very complex because of the data manifold distortions through time. We propose the use of the kernel manifold alignment (KEMA) method for…
Stieltjes Differential Inclusions with Periodic Boundary Conditions without Upper Semicontinuity
2021
We are studying first order differential inclusions with periodic boundary conditions where the Stieltjes derivative with respect to a left-continuous non-decreasing function replaces the classical derivative. The involved set-valued mapping is not assumed to have compact and convex values, nor to be upper semicontinuous concerning the second argument everywhere, as in other related works. A condition involving the contingent derivative relative to the non-decreasing function (recently introduced and applied to initial value problems by R.L. Pouso, I.M. Marquez Albes, and J. Rodriguez-Lopez) is imposed on the set where the upper semicontinuity and the assumption to have compact convex value…
The dynamics of aroma release during consumption of candies of different structures, and relationship with temporal perception
2011
; We investigated the role of both candy texture and eating technique (melting or chewing) on the dynamics of aroma release. One novelty of this type of analysis was the simultaneous application of instrumental and sensory analysis. Four candy textures were established based on their storage modulus at 1 Hz by varying the gelatine content between 0 and 15% w/w. The in vivo release of three aroma compounds was monitored using Proton Transfer Reaction Mass Spectrometry and with a trained panel of testers. The gelatine content had no significant effect on the headspace/product partition and diffusion properties of the aroma compounds. The highest in vivo release for all aroma compounds was ob…
Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora
2011
Abstract Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites, the long-term impacts of such changes on evolutionary significant units in response to past climatic change have been little documented. Here we use phylogenies to reconstruct changes in distribution and flowering ecology of the Cape flora - South Africa's biodiversity hotspot - through a period of past (Neogene and Quaternary) changes in the seasonality of rainfall over a timescale of several million years. Results Forty-three dist…
Ágora para la educación física y el deporte
2020
Resumen basado en el de la publicación Título, resumen y palabras clave disponibles en español y en inglés Se pretende analizar la motivación de los adolescentes hacia la educación física y la práctica de actividad física habitual en función del género y en función de su práctica de actividad física habitual. Para ello, se tomó una muestra de 83 estudiantes de un instituto de Educación Secundaria Obligatoria de Valencia (España), con edades comprendidas entre los 14 y 17 años (M = 15.06; DT = .79). Los instrumentos utilizados fueron el cuestionario de motivación en las clases de educación física (CMEF), que incluye la motivación intrínseca, la regulación identificada, la regulación introyec…
LEARNING THE VALUE OF TIME IN PHYSICAL EDUCATION
2021
El presente artículo analiza las prácticas pedagógicas de la Educación Física de un contexto específico para describir cómo promueven el aprendizaje del tiempo. A partir de una etnografía se obtienen las actividades propuestas por el profesorado de Educación Física de una escuela de Meliana, en Valencia (España). Se recogen 82 tareas motrices que son analizadas y contextualizadas en el marco educativo. Los resultados, a la luz de las ciencias de la educación, muestran una tendencia a realizar tareas sin memoria de resultado en las que no existe un final marcado por las reglas y, en menor tiempo, actividades con memoria en las que los participantes se clasifican en función del desenlace. La …
Facilitadores y barreras para la práctica físico-deportiva en alumnado universitario con discapacidad: un estudio cualitativo
2017
Problema: a pesar de los numerosos beneficios que aporta la actividad física a las personas con discapacidad, la tasa de inactividad en este colectivo es muy elevada. Objetivo: explorar, desde un modelo socio-ecológico, los facilitadores y barreras que influyen en la actividad física en tiempo de ocio del alumnado universitario con discapacidad. Metodología: perspectiva metodológica cualitativa. Se entrevistó en profundidad a cinco alumnos universitarios con discapacidad que realizan actividad física en su tiempo de ocio. Resultados: el análisis categorial de contenido realizado muestra facilitadores como el apoyo social, la motivación o el reconocimiento de beneficios, tanto físicos como p…
Comparing SARS-CoV-2 case rates between pupils, teachers and the general population: results from Germany
2021
Given the inconsistent state of research regarding the role of pupils and teachers during the SARS-CoV-2 pandemic in Germany, statewide and nationwide data of infection case rates were analyzed to contribute to the discourse. Infection data from official sources ranging from mid to late 2020 were collected, prepared and analyzed to answer the question if pupils, teachers and general population differ in infection case rates or not. Statewide and nationwide data showed that pupils and teachers infection case rates exceeded those of the general population. However, present data do not necessarily indicate that SARS-CoV-2 cases of pupils and teachers infections took place at schools. Actually,…
