Femtosecond‑LASIK outcomes using the VisuMax®‑MEL® 80 platform for hyperopia and hyperopic astigmatism refractive surgery

2021

The present study evaluated the efficacy, the safety and the predictability of the Femtosecond laser-assisted in situ keratomileusis (Femto-LASIK) procedure for hyperopia and hyperopic astigmatism. We retrospectively analyzed the postoperative 12-month evolution of 593 eyes with hyperopia and hyperopic astigmatism that underwent Femto-LASIK treatment. The procedure was predictable and effective. No eye lost 2 lines of corrected distance visual acuity (CDVA), demonstrating a safety profile of the procedure. Nine percent of the eyes gained at least one line of CDVA. The accuracy of the spherical equivalent after 12 months was 74% within ±1.0 diopter (D) of emmetropia. The refractive outcomes …

Prevalence of visual impairment and refractive errors in an urban area of Mexico

2019

AIM: To determine the distribution of refractive errors in a school-age population in Quintana Roo (Mexico) in the framework of an international cooperation campaign for the prevention of blindness. METHODS: A sample of 2647 school-age children (ranging from 5 to 14 years old) with a mean age of 9.1±1.9 years old were tested by trained volunteers for distance visual acuity (VA) and refractive errors. The first screening examination included uncorrected distance visual acuity (UDVA) and VA with a +2.00 D lens. Inclusion criteria for a second complete cycloplegic eye examination performed by an optometrist were UDVA <20/25 (0.10 logMAR or 0.8 decimal) and/or VA with +2.00 D ≥20/25. RESULTS: A…

O projeto Mujeres Maestras del Perú. Estudo de caso sobre identidades de ensino

2018

El proyecto «Mujeres Maestras de Perú» nos acerca a las opiniones de veintiun maestras peruanas. Las que trabajan en entornos menos favorecidos e insisten en su precocidad vocacional. Las maestras nos hablan de dicho factor vocacional como de algo que ya aparece en su infancia en tanto que deseo explícito de dedicarse a la docencia. Nuestra investigación parte de un enfoque cualitativo, mediante un estudio de caso al que incorporamos elementos de rango artístico (Investigación basada en las artes). Utilizamos grabaciones audiovisuales como instrumento de recogida de datos. Desde la educación artística, visibilizamos las identidades del colectivo docente como homenaje y reivindicación profes…

Le Rotte Mediterranee di Imago Mundi e l’immagine contemporanea della Wunderkammer

2017

Attraverso l’analisi di Rotte Mediterranee, una delle molteplici mostre itineranti di “Imago Mundi”, la collezione in progress di arte contemporanea che Luciano Benetton commissiona e raccoglie nei suoi viaggi intorno al mondo, l’articolo dimostra come questo archivio di opere sia esso stesso un’opera, un’azione di mecenatismo contemporaneo. “Imago Mundi” è un continuo viaggio di ricerca, una mappa antropologico-visuale complessa, giocata tra la raccolta materiale delle collezioni e la loro registrazione virtuale nel catalogo digitale. Per la sua struttura espositiva enciclopedica, “Imago Mundi” rimanda al modello delle Wunderkammern: un caleidoscopio di immagini dove locale e globale coesi…

Effects of menu structure and touch screen scrolling style on the variability of glance durations during in-vehicle visual search tasks.

2011

The effects of alternative navigation device display features on drivers' visual sampling efficiency while searching forpoints of interest were studied in two driving simulation experiments with 40 participants. Given that the number of display items was sufficient, display features that facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations. As predicted, compared with a grid-style menu, searching information in a list-style menu while driving led to smaller variance in durations of in-vehicle glances, in particular with nine item displays. Kinetic touch screen scrolling induced a greater number of very short in-v…

Psicothema

2016

Resumen tomado de la publicación ¿Cómo codifican los jugadores de Scrabble la posición de las letras durante la lectura? Antecedentes: en experimentos con lectores adultos, las pseudopalabras creadas por transposición de letras (v.g., CHOLOCATE) se confunden frecuentemente con su palabra base. Por ejemplo, en tareas de decisión léxica (“¿es el estímulo una palabra?”), los tiempos de respuesta son mayores y con mayor porcentaje de errores para CHOLOCATE que para su control ortográfico CHOTONATE (es decir, un efecto de transposición de letras). Método: en el presente experimento examinamos los procesos de codificación de la posición de las letras en individuos particularmente expertos en el p…

On the relationship between occlusion times and in-car glance durations in simulated driving

2023

Drivers have spare visual capacity in driving, and often this capacity is used for engaging in secondary in-car tasks. Previous research has suggested that the spare visual capacity could be estimated with the occlusion method. However, the relationship between drivers’ occlusion times and in-car glance duration preferences has not been sufficiently investigated for granting occlusion times the role of an estimate of spare visual capacity. We conducted a driving simulator experiment (N = 30) and investigated if there is an association between drivers’ occlusion times and in-car glance durations in a given driving scenario. Furthermore, we explored which factors and variables could explain t…

Sulle orme del consumatore affinity analysis e knowledge visualization per il processo decisionale

2016

L’articolo analizza i reali comportamenti di acquisto dell’acquirente all’interno del punto vendita e individua i pattern latenti più significativi attraverso un’analisi di affinità di 128.364 scontrini estratti da un dataset di 715.662 transazioni effettuate in un anno. Lo studio individua le strutture associative più ricorrenti relativamente alla singola merceologia. Attraverso la tecnica della Market Basket Analysis è stato possibile individuare le categorie merceologiche che creano “poli d’attrazione” sul punto vendita stimolando acquisti di altre categorie. In particolar modo, applicando le regole associative sul punto vendita è stato possibile identificare le “aree calde” e le “aree f…
