Competenza digitale e saggezza a scuola
2014
La scuola costituisce un luogo privilegiato -certamente una delle esperienze centrali nella vita dei giovani- di inserimento sociale, di partecipazione e di confronto; ma soprattutto si pone come banco di prova per la costruzione del sé, dei propri valori, dei propri modi di rapportarsi al mondo circostante, delle proprie strategie per affrontare la realtà, della propria autostima, delle aspettative di efficacia. Le nuove tecnologie costituiscono delle risorse di cui non si può fare a meno. Ma quando i ragazzi, non riuscendo a stabilire una relazione fiduciaria con i loro insegnanti, si chiudono in una dimensione quasi “de-realistica” corrono il rischio di restare in balia dei media, di non…
Competenze docimologiche degli insegnanti di scuola primaria e dell’infanzia
2008
Nel contributo si mette in luce come, attraverso il modo di valutare, sia possibile orientare e dare autonomia al processo di apprendimento, il che significa: rilevare l’interesse e la motivazione dello studente verso particolari argomenti; responsabilizzarlo nel suo processo di apprendimento; orientarlo nelle scelte formative; valorizzare i suoi processi metacognitivi; promuovere la motivazione intrinseca allo studio. Le competenze preludono al diritto all’apprendimento e alla formazione in termini di lunga durata; richiamano processi di pensiero complessi in cui, attraverso idee, concetti e paradigmi, si promuove la personalizzazione delle esperienze conoscitive. Preludono, altresì, ad un…
Verso un’ecologia dei conflitti: G. Bateson e la gestione pedagogica delle differenze

B and T lymphocytes are affected in lysosomal disorders--an immunoelectron microscopic study.
1991
Circulating lymphocytes of four patients with mucopolysaccharidoses II and IIIA, four patients with juvenile neuronal ceroid-lipofuscinosis, one patient each with glycogenosis type II, infantile neuronal ceroid-lipofuscinosis, and Gaucher disease were classified by immunoelectron microscopy as B or T lymphocytes. Disease-specific lysosomal inclusions as well as non-specific lysosomal organelles, especially Gall bodies were identified in B and T lymphocytes. These non-quantitative studies indicate that both B and T lymphocytes participate in the lysosomal storage process.
Itinerarios De M-Learning en La Educación Universitaria
2015
In recent years, mobile devices like smartphones, tablets, and laptops allow immediate connection and content exchange among people "anytime, anywhere" (Park S.Y., et al. 2012). 'Ubiquitous learning’ becomes very important in higher and university education also in order to emphasize the educational paths’ design and maximize students’ learning opportunities. At this regard, it‘s interesting to consider the assumptions of the connectivism theory (Siemens, 2005) as a theoretical reference for the e-learning design. For verifying these assumptions and clarifying whether Italian teachers and students share them, we conducted this research. This empirical study aims to grasp what type of mobile…
Predator mimicry, not conspicuousness, explains the efficacy of butterfly eyespots
2015
Large conspicuous eyespots on butterfly wings have been shown to deter predators. This has been traditionally explained by mimicry of vertebrate eyes, but recently the classic eye-mimicry hypothesis has been challenged. It is proposed that the conspicuousness of the eyespot, not mimicry, is what causes aversion due to sensory biases, neophobia or sensory overloads. We conducted an experiment to directly test whether the eye-mimicry or the conspicuousness hypothesis better explain eyespot efficacy. We used great tits ( Parus major ) as model predator, and tested their reaction towards animated images on a computer display. Birds were tested against images of butterflies without eyespots, wi…
Protective coloration of European vipers throughout the predation sequence
2020
Antipredator adaptations in the form of animal coloration are common and often multifunctional. European vipers (genus Vipera) have a characteristic dorsal zigzag pattern, which has been shown to serve as a warning signal to potential predators. At the same time, it has been suggested to decrease detection risk, and to cause a motion dazzle or flicker-fusion effect during movement. We tested these hypotheses by asking whether (1) the zigzag pattern decreases detection risk and (2) the detection is dependent on the base coloration (grey or brown) or the snake's posture (coiled, basking form or S-shaped, active form). Additionally, (3) we measured the fleeing speed of adders, Vipera berus, an…
Maineen ja tunnettuuden merkitys yhteishyvään pyrkivän organisaation legitimiteetin muodostumisessa
2010
Kolmannen sektorin merkitys yhteiskunnassa on vahvistunut. Yhteishyvään pyrkivien kolmannen sektorin organisaatioiden voi kuitenkin olla vaikeaa saavuttaa legitiimi asema, jossa niiden toimintaa pidetään riittävän tarpeellisena. Imagoilla, maineella ja tunnettuudella voidaan nähdä olevan suuri vaikutus legitimiteetin muodostumiseen ja säilyttämiseen toimintakentällä. Yhteishyvään pyrkivien organisaatioiden aineettomien ominaisuuksien merkitystä legitimiteetille ei kuitenkaan ole tutkittu paljon. Tutkimuksen tavoitteena oli selvittää, miten yhteishyvään pyrkivän organisaation tunnettuus, mielikuvat ja maine tärkeiden sidosryhmien keskuudessa vaikuttavat legitimiteetin muodostumiseen, ja mite…
