Embodied graffiti and street art research
2021
Graffiti and street art research (GSAR) has become more acknowledged within the academic discourse; however, it has much to gain from theorising its methodological aspects. As a multidisciplinary field, GSAR has mostly used qualitative research methods, exploring urban space through methods that range from visual recordings to ethnography, emphasising the researchers’ reflexivity. This qualitative approach has, however, paid little attention to the role of embodied practices. In this paper we discuss how embodied methodologies provide multisensory research results where the experienced moments, the participant’s and researcher’s senses, cognition and mobility in urban spaces are connected.…
A Methodology for Protection of Trees Against Lightning Strikes as a Measure to Prevent Fires and Loss of Human Life
2021
Some regions may be characterized by a very low annual lightning ground flash density, and yet lightning strikes seem to have been in those areas the cause of widespread wildfires in forested areas. Due to global climate change, these occurrences seem to be an increasing threat. In this paper, the authors discuss the withstand capability of trees against lightning and introduce the criteria for the deployment of tree lightning protection systems (TLPS) to protect forested areas, where deemed necessary by the tree risk assessment. This work analytically identifies the critical trunk radius of the tree below which the tree may explode in the case of a lightning strike and ignite the surroundi…
25 años de graffiti en Valencia: aspectos sociológicos y estéticos
2015
La Tesis Doctoral "25 Años de Graffiti en Valencia: Aspectos Sociológicos y Estéticos" es un estudio que pone en valor todo el espectro de las escenas de graffiti y creatividad pública independiente -Street Art- de la ciudad de Valencia. El marco teórico del estudio son los Estudios Culturales, Subculturales y Postsubculturales. La metodología específica de su abordaje es la Observación Participante. El estudio se inicia con el análisis de los precedentes visuales, actitudinales y estratégicos de las prácticas del graffiti y la creatividad pública independiente: el cómic, el cartoon animado, la cultura popular, el cine, la televisión,la rotulación comercial, el diseño gráfico y la contracul…
LOW VIGOR PEACH × ALMOND ROOTSTOCKS FOR INTENSIVE PEACH PLANTINGS IN MEDITERRANEAN ENVIRONMENTS
2014
A three-year trial was carried out to evaluate the vegetative and productive performance of five peach rootstocks of varied vigor. The study was conducted in south-western Sicily using 45 V-trained trees of 'Tropic Snow' peach planted in 2005 and grafted on GF677 and four low-vigor rootstocks selected at the Department of Agricultural, Food and Environmental Sciences, University of Pisa, namely IS5/8 (Polluce), IS5/19 (Castore), IS5/23, IS5/29. Trunk circumference, winter and summer pruning weight, number and mass of fruit were recorded from 2010 to 2012. All IS selections reduced trunk cross-sectional area (TCSA) and pruning weight compared to GF677 with IS5/23 inducing the highest reducti…
KERNEL ESTIMATION OF THE TRANSITION DENSITY IN BIFURCATING MARKOV CHAINS
2023
We study the kernel estimator of the transition density of bifurcating Markov chains. Under some ergodic and regularity properties, we prove that this estimator is consistent and asymptotically normal. Next, in the numerical studies, we propose two data-driven methods to choose the bandwidth parameters. These methods are based on the so-called two bandwidths approach.
The trees in the middle of Paradise (Gn 2:9) during the Great Lent: Orthodox hymnography as biblical interpretation
2022
The article examines the interpretation of the Scripture in Byzantine hymnography during the Great Lent. Some notable recent contributions focus on Andrew of Crete’s and Romanos the Melodist’s compositions, illustrating the hymnographic way of understanding the Scriptures. The author of this study presents a selection of stanzas from hymns of the Triodion that refer to the trees of Paradise. Hymnography perceives the trees in Genesis 2–3 in direct connection with the cross. Only rarely is the tree of life a metaphor for Jesus, as the shadow of the tree of the cross is seldom a metaphor for protection. Another interesting aspect in relation to hymnography is the fact that it represents a typ…
Les plaques-boucles mérovingiennes ornées d'une croix encadrée par deux griffons : à propos d'une découverte faite à Fleurey-sur-Ouche (Côte-d'Or)
2010
The presentation of this copper alloy belt buckle decorated with a cross flanked by two griffons from Fleurey-sur- Ouche (Côte-d'Or), gives us the opportunity to review our knowledge of this type of buckle, the corpus of which has been recently enriched by new examples. Even though the fifteen known pieces can be categorized in the group D defined by the characteristic finds of the Burgundian kingdom, the iconographical theme remains quite diverse. Also, discoveries have been made all over this vast area, underlining the existence of several workshops, not only in the Jura put also in the Lauragais area.
DeTreex Inductive Knowledge Acquisition System in Project Risk Assessment
2016
The aim of this paper is to present the possibility of employing DeTreex inductive knowledge acquisition system in project risk assessment. DeTreex from AITECH Artificial Intelligence Laboratory is a system for knowledge acquisition implementing the inductive machine learning method. Induction in the knowledge acquisition system draws on the induction of decision trees proposed by Quinlan. DeTreex was used to carry out the analysis of data elaborated for the purposes of project risk assessment.The problem of acquisition of knowledge of potential project risk sources, the structuring and processing of such knowledge is, in the case of project management, a relatively new and not fully resear…

POPOLAMENTI MARGINALI DI FAGGIO E CAMBIAMENTI CLIMATICI IN SICILIA: CRITICITÀ ED EFFETTI DELL’APPLICAZIONE DI PRATICHE SELVICOLTURALI TRADIZIONALI NO…
2016
Il faggio (Fagus sylvatica) è una tipica specie medio-Europea; in Sicilia si rinvengono i boschi di faggio più meridionali d’Europa. La marginalità ecologica di questi boschi è particolarmente evidente nei pattern frammentati e isolati di questi soprassuoli, in prossimità del limite della vegetazione arborea e/o localizzati nelle condizioni topografiche meno favorevoli. Nel presente lavoro si mettono a confronto i parametri dendrometricostrutturali e lo stato di salute delle piante in soprassuoli delle Madonie, confrontando cedui di faggio recentemente sottoposti a pratiche di taglio e aree di controllo non trattate da tempo. Inoltre, questi aspetti sono stati messi in relazione con il grad…
