Adaptación transcultural al español y validez de contenido de 3 escalas de riesgo nutricional
2022
Introduction: There are various scales designed to determine the risk of malnutrition at hospital admission in children. However, most of these instruments are developed and published in English. Their cross-cultural adaptation and validation being mandatory in order to be used in our country. Objectives: Cross-culturally adapt three scales designed to determine the risk of malnutrition linked to the disease and determine the validity of their content. Material and methods: Cross-cultural adaptation using the translation-back-translation met-hod in accordance with the recommendations of the International Test Commission Guidelines for Translating and Adapting Tests. Content validity was mea…
A non-parametric Scale-based Corner Detector
2008
This paper introduces a new Harris-affine corner detector algorithm, that does not need parameters to locate corners in images, given an observation scale. Standard detectors require to fine tune the values of parameters which strictly depend on the particular input image. A quantitative comparison between our implementation and a standard Harris-affine implementation provides good results, showing that the proposed methodology is robust and accurate. The benchmark consists of public images used in literature for feature detection.
Application of action camera video for fast and low-cost photogrammetric survey of cultural heritage
2022
Abstract. The research work focuses on the growing of fast and low-cost data surveying methods (both in the acquisition and processing phases), to be used mainly as a support for the management and enhancement of architectural heritage. Attention is paid on the diffusion of action cameras, characterized by wide-angle lenses and 4K video shooting, with more and more affordable prices and on the elaboration of the data with photogrammetry software. The high-resolution videos captured by these tools, in fact, allow the selection of frames characterized by sufficient overlap, necessary for point cloud generation through Structure for Motion (SfM) processes. The focus is on indoor environment ch…
Logit analysis in L2 research: measuring L1 and L2/Ln effects
1998
In quantitatively oriented L2 studies, we normally contrast two phenomena at a time, both at the group and individual level. However, it is generally acknowledged that what a learner produces is determined by a multitude of factors influencing the interlanguage (IL) simultaneously. When dealing with discrete, nominal categories, the numerical and causal relations between the variables involved cannot be adequately captured in an analysis where the phenomenon to be studied and the explanatory factors are subjected to a series of pairwise statistical tests. Instead of the two-variable approach, multivariate techniques should be applied, since they allow for the examination of the effects of m…
Visual and optical performance with hybrid multifocal intraocular lenses
2010
During the past years, the wish to become independent of spectacles has been growing among cataract and presbyopic patients due to many factors, such as the increase in near visual demands, the aesthetic need for a spectacle-free image and ageing of refractive surgery patients, among others. This review assesses recently published studies that analyse visual and optical performance through different metrics of eyes implanted with multifocal intraocular lenses (IOLs), particularly hybrid IOL designs. The published evidence suggests that hybrid multifocal IOLs provide very good outcomes in a number of visual and optical performance parameters. Patients implanted with this type of IOL obtain a…
El tòpic cavalleresc de la insularitat en l’Amadís, el Tirant i el Quijote
2013
En el present estudi s’incideix en la importància que té l’espai físic de les illes en les narracions cavalleresques. En concret, fixem la nostra atenció en tres grans obres de les literatures peninsulars: l’Amadís de Gaula, el Tirant lo Blanc i Don Quijote de la Mancha. S’hi analitza el paper que tenen aquestos escenaris en l’esdevenidor de la història i en la trajectòria dels diferents personatges des d’una òptica comparatista, la finalitat de la qual és continuar establint l’extensió i els límits de les seues relacions. This study provides an overview of the physical space of the islands in the chivalry’s narratives. Specifically, we focus on three major works of peninsular literature: A…
Physical play - How do we inspire and motivate young children to be physically active through play? An international analysis of twelve countries’ na…
2023
Lifelong movement and physical activity (PA) patterns develop during early childhood. Therefore, educators (teachers and practitioners) in early childhood education and care (ECEC) should provide opportunities to support children’s play, PA, and movement development. The World Health Organization (2019) offers new recommendations for PA, for children under five years. The guidelines do not specify the ways ECEC staff can support PA through play. Therefore, this paper investigates, how physical play (PP) is enacted globally. An international policy and practice analysis of twelve countries, (Australia [Victoria], Belgium [Flanders], Canada [Alberta], China, Finland, Ireland, Italy, Portugal,…

Yellow (577 nm) micropulse laser versus half-dose verteporfin photodynamic therapy in eyes with chronic central serous chorioretinopathy: results of …
2018
PurposeTo compare the functional and anatomical outcomes of eyes with chronic central serous chorioretinopathy treated with yellow micropulse (MP) laser versus half-dose verteporfin photodynamic therapy (PDT).MethodsThis is a multicentre, retrospective comparative study of 92 eyes treated with yellow MP laser (duty cycle of 5%, zero spacing between spots, spot size varied from 100 to 200 µm, power varied from 320 to 660 mW, and the pulse burst duration was 200 ms) and 67 eyes treated with PDT (half-dose verteporfin (3 mg/m2) infused over 10 min), followed by laser activation for 83 s. Spot sizes varied from 400 to 2000 µm.ResultsIn the MP group, at 12 months of follow-up, the mean best corr…
