Valutazione partecipata e continuità nei servizi educativi zero-sei: una ricerca-intervento in un quartiere della città di Palermo
2021
RIASSUNTO In questo articolo verrà condotta inizialmente una riflessione sulla funzione della valutazione di contesto sia in termini formativi individuali e di gruppo, sia in termini di cambiamento organizzativo, adottando una prospettiva ecologica e sistemica. Successivamente, attraverso la narrazione di un percorso di ricerca sulla costruzione di un possibile curricolo zero-sei, condotta per tre anni con un gruppo di insegnanti di scuola dell’infanzia statale ed un gruppo di educatrici di un nido comunale operanti nello stesso territorio (un quartiere del centro storico di Palermo), verranno messi in luce e problematizzati ambiti di continuità e di discontinuità tra i due servizi educativ…
The keyboard as a part of visual, auditory and kinesthetic processing in sight-reading at the piano
2009
Sight-reading at the piano requires coordination of multiple modalities—visual, auditory, and kinesthetic. Visual feedback (obtained by looking at the keyboard and the fingers) is usually regarded as one means by which pianists guide musical performance, but few researchers have focused on the organisational aspects implicit in the information provided by the keyboard. This study investigated the role of the keyboard with respect to the visual, auditory, and kinesthetic modalities involved in sight-reading. Five pianists sight-read two compositions, each in a different musical style. They were then interviewed in a semi-structured interview format. A qualitative content analysis was made fr…
Lethal and behavioural effects of a green insecticide against an invasive polyphagous fruit fly pest and its safety to mammals
2021
Abstract Plant essential oil-based insecticides, with special reference to those that may be obtained from largely available biomasses, represent a valuable tool for Integrated Pest Management. However, the sublethal effects and the potential effects on aggressive insect traits of these green insecticides are understudied. Herein, the lethal and sub-lethal effects of the carlina oxide, constituting more than 97% of the whole Carlina acaulis (Asteraceae) root essential oil (EO), were determined against an invasive polyphagous tephritid pest, Ceratitis capitata (medfly). The carlina oxide was formulated in a mucilaginous solution containing carboxymethylcellulose sodium salt, sucrose, and hyd…

Abstract Essential oil (EO)-based botanical insecticides are considered a promising option for Integrated Pest Management (IPM). However, the sublethal effects of EO-based insecticides are understudied. No information is available on the potential effects of EO exposure on insect aggressive traits. In this study, the toxicity of two EOs with documented efficacy on insect vectors and agricultural pests, and which were obtained from the roots of silver thistle (Carlina acaulis L., Asteraceae) and seeds (i.e. schizocarps) of ajwain (Trachyspermum ammi (L.) Sprague, Apiaceae), was evaluated against adults of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (medfly), a cosmopolitan fr…
Updated single and dual crop coefficients for tree and vine fruit crops
2021
Abstract The present study reviews the research on the FAO56 crop coefficients of fruit trees and vines performed over the past twenty years. The main objective was to update information and extend tabulated single (K c ) and basal (K cb ) standard crop coefficients. The selection and analysis of the literature for this review have been done to consider only studies that adhere to FAO56 method, computing the reference ET with the FAO Penman–Monteith ET o equation and field measuring crop ET with proved accuracy. The crops considered refer to vine fruit crops, berries and hops, temperate climate evergreen fruit trees, temperate climate deciduous fruit trees and, tropical and subtropical fru…
El valor del establecimiento y su relación con la imagen de marca privada: efecto moderador del conocimiento de la marca privada como oferta propia d…
2013
ResumenEl presente trabajo plantea como objetivo conocer cómo afecta la imagen de marca privada a la formación del valor de marca del establecimiento; en el estudio de esta relación cobra especial consideración la posible influencia del conocimiento de la marca privada como oferta propia del establecimiento. Desde una perspectiva empírica, se analizan los establecimientos Decathlon, a partir de la opinión de 300 consumidores. Los resultados obtenidos en la investigación muestran la importancia de fortalecer una imagen de marca privada positiva y favorable, como medio para la construcción de una sólida imagen de la tienda que, a su vez, también repercute en la creación del valor del establec…
Long-term effects on cortical glutamate release induced by prenatal exposure to the cannabinoid receptor agonist (r)-(+)-[2,3-dihydro-5-methyl-3-(4-m…
2003
The aim of the present in vivo microdialysis study was to investigate whether prenatal exposure to the CB1 receptor agonist WIN55,212-2 mesylate (WIN; (R)-()-(2,3- dihydro-5-methyl-3-(4-morpholinyl-methyl)pyrrolo(1,2,3-de)- 1,4-benzoxazin-6-yl)-1-naphthalenylmethanone), at a dose of 0.5 mg/kg (s.c. from the fifth to the 20th day of gestation), that causes neither malformations nor overt signs of toxicity, influences cortical glutamate extracellular levels in adult (90- day old) rats. Dam weight gain, pregnancy length and litter size at birth were not significantly affected by prenatal treatment with WIN. Basal and K-evoked dialysate glutamate levels were lower in the cerebral cortex of adul…
Prenatal exposure to the CB1 receptor agonist WIN 55,212-2 causes learning disruption associated with impaired cortical NMDA receptor function and em…
2005
The aim of this study was to investigate whether prenatal exposure to the cannabinoid CB1 receptor agonist WIN 55,212-2 (WIN) at a daily dose devoid of overt signs of toxicity and/or gross malformations (0.5 mg/kg, gestation days 5-20), influences cortical glutamatergic neurotransmission, learning and emotional reactivity in rat offspring. Basal and K+-evoked extracellular glutamate levels were significantly lower in cortical cell cultures obtained from pups exposed to WIN during gestation with respect to those measured in cultures obtained from neonates born from vehicle-treated dams. The addition of NMDA to cortical cell cultures from neonates born from vehicle-treated dams concentration-…
Cardiac Troponins for the Diagnosis of Acute Myocardial Infarction in Chronic Kidney Disease
2018
Background Patients with chronic kidney disease ( CKD ) are at high risk of myocardial infarction. Cardiac troponins are the biomarkers of choice for the diagnosis of acute myocardial infarction ( AMI ) without ST ‐segment elevation ( NSTE ). In patients with CKD , troponin levels are often chronically elevated, which reduces their diagnostic utility when NSTE ‐ AMI is suspected. The aim of this study was to derive a diagnostic algorithm for serial troponin measurements in patients with CKD and suspected NSTE ‐ AMI . Methods and Results Two cohorts, 1494 patients from a prospective cohort study with high‐sensitivity troponin I (hs‐ cTnI ) measurements and 7059 cases from a clinical registr…
Nouvelles données sur les Asellidae épigés d’Extrême-Orient (Crustacea, Isopoda, Asellota)
1995
Numerous samples of oculate Asellus from eastern Siberia and the Japanese Islands, one from southern China, and one from Alaska, have been studied. The epigean fresh waters of this large Asiatic region generally harbour populations identified as Asellus (Asellus) hilgendorfii Bovallius, 1886, or some of its geographical forms previously considered as species, subspecies, or not yet named. The “hilgendorfii” complex seems to possess the dimension of a superspecies. A new pigmented-oculate species, Asellus (Asellus) levanidovorum is sympatric with A. (A.) hilgendorfii in the lake Bolon region (lower part of the Amur River basin) and is present also in the Sakhalin and Kunashir Islands. Its co…
