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…
Full-parallax immersive 3D display from depth-map cameras
2016
We exploit two different versions of the Kinect to make comparison of three-dimensional (3D) scenes displayed by proposed integral imaging (InI) display system. We attempt to show the difference between each version specifications and capacity. Furthermore, we illustrate our study result with some empirical imaging experiment in which the final result are displayed with full-parallax. Each demonstrated integral images can provide clear comparison results to the observer.
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…
Hybridization in Capparis spinosa L.: Molecular and morphological evidence from a Mediterranean island complex
2014
Inter-Simple Sequence Repeat (ISSR) molecular markers and morphological analysis were used in order to characterize wild populations and cultivated forms of orphan crop species Capparis spinosa L. in a Mediterranean island complex. Nineteen wild populations belonging to two different subspecies, C. spinosa subsp. spinosa and subsp. rupestris, were sampled in different environments in Sicily and the surrounding islets Lampedusa, Pantelleria and Salina. Different biotypes cultivated in Pantelleria and Salina were analyzed. Six ISSR primers were selected for genetic characterization, and all clear and reproducible bands were scored and analyzed. Among the 47 ISSR bands obtained, 97.5% were pol…
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…
Der kontaminierte Hippokrates: Textkritischer Wert und Vorlagen der Handschrift Parisinus gr. 2142.
2014
Il manoscritto Parisinus Graecus 2142 è uno dei più antichi ed importanti tra i cosiddetti codici recenziori della tradizione manoscritta del corpus ippocratico, e si presta particolarmente per la sua natura bipartita e contaminata ad essere riesaminato dal punto di vista del suo valore per l'editore di testi ippocratici. Una tale analisi critica non può prescindere dal problema delle origini delle contaminazioni cui le diverse mani che hanno vergato il Parisinus avrebbero avuto accesso. L'analisi dettagliata delle diverse mani correttrici e del loro apporto alla constitutio del testo di un campione significativo di scritti ippocratici mostra il particolare rilievo del Parisinus, specie del…
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…
