Discrimination of astringent and deastringed hard ‘Rojo Brillante’ persimmon fruit using a sensory threshold by means of hyperspectral imaging
2019
[EN] Persimmon fruit cv. 'Rojo Brillante' is an astringent cultivar due to its content of soluble tannins, which are insolubilised during the ripening of the fruit. Traditionally, the consumption of this cultivar has only been possible when the fruit is overripe and the texture is soft. Postharvest treatments based on exposing fruits to high CO2 concentrations allow astringency removal while preserving high flesh firmness. However, the effectiveness of this treatment is controlled by means of slow destructive methods. The aim of this work is to study the application of hyperspectral imaging in the spectral range 450-1040 nm to discriminate astringent (A) and deastringed (DA) fruits non-dest…
Consumer Neuroscience-Based Metrics Predict Recall, Liking and Viewing Rates in Online Advertising
2017
[EN] The purpose of the present study is to investigate whether the effectiveness of a new ad on digital channels (YouTube) can be predicted by using neural networks and neuroscience-based metrics (brain response, heart rate variability and eye tracking). Neurophysiological records from 35 participants were exposed to 8 relevant TV Super Bowl commercials. Correlations between neurophysiological-based metrics, ad recall, ad liking, the ACE metrix score and the number of views on YouTube during a year were investigated. Our findings suggest a significant correlation between neuroscience metrics and self-reported of ad effectiveness and the direct number of views on the YouTube channel. In add…
Virtual Reality in Marketing: A Framework, Review, and Research Agenda
2019
[EN] Marketing scholars and practitioners are showing increasing interest in Extended Reality (XR) technologies (XRs), such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), as very promising technological tools for producing satisfactory consumer experiences that mirror those experienced in physical stores. However, most of the studies published to date lack a certain measure of methodological rigor in their characterization of XR technologies and in the assessment techniques used to characterize the consumer experience, which limits the generalization of the results. We argue that it is necessary to define a rigorous methodological framework for the use of XRs in ma…
Constructing relational space in early childhood education
2014
This paper examines early childhood education (ECE) by applying and developing relational-spatial perspectives on everyday life in educational institutions for young children. The aim is to investigate the dynamic process of construction of space and to illustrate with selected empirical episodes how this process occurs in ECE. Drawing on authors such as Soja and Bourdieu, the starting point for the analysis is that space is socially produced in everyday interactions in a process that intertwines the physical environment and concrete objects, personal interpretations of physical and cultural space, and cultural and collective views about space in ECE. We illustrate this process with ethnogr…
Kindergarten space and autonomy in construction - Explorations during team ethnography in a Finnish kindergarten
2018
Abstract Children’s autonomy is a cultural ideal in Finnish early childhood education and care (ECEC). In this article we examine autonomy in spatial terms. The theoretical background is developed by applying spatial sociology. Our starting point is that space is relationally produced, thus, we understand space as continuously negotiated, reconstructed and reorganized phenomena. In this article, we investigate the production of space by different actors in ECEC and seek to show how autonomy is also continuously produced and re-produced in the negotiation of space. For this investigation we use data collected as part of a team ethnographic project in a Finnish kindergarten. The project inclu…
Illustrating a Family. The Printing Press and Political Issues in the "Ritratti della Prosapia et Heroi Moncadi nella Sicilia"
2021
In an early printed book, the presence of a large iconographic apparatus normally reveals a strong effort both in designing its shape and in the financial coverage needed to make it possible. Such effort can be fully explained by paying attention to the scope and target behind its conception. The two volumes of “Ritratti della Prosapia et heroi Moncadi nella Sicilia”, published in 1657 in Valencia, offer a notable example of the political exposure sought after by a noble family, that of Moncada, through the printing press technique and its power of circulation, combined with the attractiveness of family portraits. In particular, the 1657 book, written by Giovanni Agostino Della Lengueglia, …
La imagen de la Concha de Oro en los impresos de la Edad Moderna
2020
For centuries, an image commonly associated with Santiago de Compostela (the shell) has accompanied the city of Palermo as well. Since the classical tradition and medieval literature, and then during the Renaissance and Baroque age, this symbol has been connected with other urban symbols (the rivers, the eagle and trhe Genius of Palermo), thus contributing to its historical identity, although in a rather idealistic form. Therefore, the expression «Golden Shell» has been used repeatedly in a large number of books printed during the Modern Age, with multiple meanings. The main purpose was to show those attributes linked with the city's landscape (wealth and beauty) within a specific political…
Special Section Guest Editorial: Advances in Agro-Hydrological Remote Sensing for Water Resources Conservation
2018
This special section focuses on the use of remote sensing tools in some of these areas, including monitoring the volume and turbidity in lake fresh water resources, retrieving soil organic matter from spectral information with particular attention to abandoned croplands and areas affected by wildfires, and identification and monitoring of natural and agricultural vegetation through emerging techniques such as shallow and deep learning algorithms. These data mining and analysis approaches are particularly promising and include convolutional neural network and the application of back propagation neural network algorithms for soil water content monitoring and the extraction of other canopy inf…
Batch Methods for Resolution Enhancement of TIR Image Sequences
2015
Thermal infrared (TIR) time series are exploited by many methods based on Earth observation (EO), for such applications as agriculture, forest management, and meteorology. However, due to physical limitations, data acquired by a single sensor are often unsatisfactory in terms of spatial or temporal resolution. This issue can be tackled by using remotely sensed data acquired by multiple sensors with complementary features. When nonreal-time functioning or at least near real-time functioning is admitted, the measurements can be profitably fed to a sequential Bayesian algorithm, which allows to account for the correlation embedded in the successive acquisitions. In this work, we focus on appli…
Soil Water Content Assessment: Critical Issues Concerning the Operational Application of the Triangle Method
2015
Knowledge of soil water content plays a key role in water management efforts to improve irrigation efficiency. Among the indirect estimation methods of soil water content via Earth Observation data is the triangle method, used to analyze optical and thermal features because these are primarily controlled by water content within the near-surface evaporation layer and root zone in bare and vegetated soils. Although the soil-vegetation-atmosphere transfer theory describes the ongoing processes, theoretical models reveal limits for operational use. When applying simplified empirical formulations, meteorological forcing could be replaced with alternative variables when the above-canopy temperatu…
