L’innovazione tecnologica e il Faculty Development.
2023
La crisi pandemica ha accelerato la diffusione di ambienti di apprendimento caratterizzati dall'uso intensivo della tecnologia. Questa novità rappresenta un obiettivo trasversale della professionalizzazione del docente universitario, con una particolare declinazione sul versante pedagogico-didattico-valutativo quale questione strategica per lo sviluppo dell’alta formazione. Il contributo illustra i risultati di una ricerca condotta con 119 docenti universitari neoassunti e 20 Direttori di dipartimento. La finalità della ricerca è stata, da una parte, rilevare la percezione dei docenti neoassunti relativa alle proprie competenze didattiche, metacognitive e valutative, con riferimento alla di…
Diagrammatic approach to cellular automata and the emergence of form with inner structure
2018
We present a diagrammatic method to build up sophisticated cellular automata (CAs) as models of complex physical systems. The diagrams complement the mathematical approach to CA modeling, whose details are also presented here, and allow CAs in rule space to be classified according to their hierarchy of layers. Since the method is valid for any discrete operator and only depends on the alphabet size, the resulting conclusions, of general validity, apply to CAs in any dimension or order in time, arbitrary neighborhood ranges and topology. We provide several examples of the method, illustrating how it can be applied to the mathematical modeling of the emergence of order out of disorder. Specif…
Wearing glasses to hear differently? Aftereffects of visuomanual prismatic adaptation on auditory perception
2022
Sensorimotor plasticity is defined as the ability to produce an appropriate motor response face to environmental or bodily changes. The classical experimental paradigm to study sensorimotor plasticity is prism adaptation, which consists of pointing to visual targets while wearing prisms that shift the visual field laterally or vertically. Its aftereffects are not restricted to sensorimotor behavior but extend to sensorial modalities not directly involved during prism exposition, such as audition. There exists a mental representation of auditory frequencies in which low auditory frequencies are associated with the left part of space and high auditory frequencies with the right part of space.…
Sensory adaptation of antennae and sex pheromone-mediated flight behavior in male oriental fruit moths (Leptidoptera: Tortricidae) after prolonged ex…
2013
Sensory adaptation has been measured in the antennae of male Grapholita molesta (Busck) after 15 min of exposure to its main pheromone compound (Z)-8-dodecen-1-yl acetate (Z8-12:OAc) at the aerial concentration of 1 ng/m(3) measured in orchards treated with pheromone for mating disruption. Exposing males to this aerial concentration of Z8-12:OAc for 15 min, however, had only a small effect on their ability to orientate by flight to virgin calling females in a flight tunnel. Experiments were undertaken to determine if exposure to the main pheromone compound in combination with the two biologically active minor compounds of this species, (E)-8-dodecen-1-yl acetate (E8-12:OAc) and (Z)-8-dodece…
Assessing teacher leadership in physical education: the Spanish version of the transformational teaching questionnaire
2018
<p>Drawing from the transformational leadership theory, this study aims to translate and analyse the psychometric properties of a Spanish version of the Transformational Teaching Questionnaire (TTQ).</p><p>A cohort sample of 2107 adolescents (997 males and 1110 females) from 82 secondary schools voluntarily participated in the research.</p><p>In Study 1 ((<em>n</em> = 1066), the exploratory factor analysis informed a one-factor solution. In Study 2 (<em>n</em> = 1041), the confirmatory factor analysis showed the single-factor and the four-factor models showed satisfactory and adequate goodness of fit indices, respectively. Confirmatory …
Life-history trade-offs in a generalist digenean from cetaceans: the role of host specificity and environmental factors
2015
Background Adults and larvae of generalist parasites are exposed to diverse hosts and local environmental conditions throughout their life cycles, thus local adaptation is expected to occur through phenotypic plasticity and/or natural selection. We investigated how the combined effect of cryptic host specificity and local selective pressures could shape reproductive traits of a putative generalist parasite in the oceanic realm. Methods The LSU rDNA, ITS2 and the mt-COI of individuals of the digenean Pholeter gastrophilus (Kossack, 1910) Odhner, 1914 (Heterophyidae Leiper, 1909) from oceanic striped dolphins, Stenella coeruleoalba Meyen, and coastal bottlenose dolphins, Tursiops truncatus Mo…
Adaptation of young teachers at school
2006
Straipsnyje aptariama, kaip Baltijos šalių mokyklose įgyvendinamas (2004–2007) Latvijos mokslo tarybos parengtas jaunųjų mokytojų adaptacijos projektas pirmaisiais darbo metais. Tyrimo dalyviai – 362 Rygos (Latvija), Klaipėdos (Lietuva) ir keturių Latvijos rajonų mokytojai, aukštąsias pedagogines mokyklas baigę 1995–2004 metais. Straipsnyje pateikiami mokslinio tyrimo rezultatai, rodantys mokytojų adaptaciją mokykloje skatinančius ir jai trukdančius veiksnius, vertinamas jaunųjų mokytojų psichologinis pasirengimas dirbti mokykloje. Respondentų teigimu, aukštosiose mokyklose apie pedagoginį darbą teikiama informacija yra objektyvi, jaunieji mokytojai jau pirmaisiais darbo metais sėkmingai ad…
La salvación de los clásicos: las adaptaciones fieles al original
2013
En este ensayo me propongo esbozar un posible procedimiento para adaptar con fidelidad un texto clásico teniendo como objetivo esencial la trasmisión de los tesoros que encierra, pero con un total respeto no solo a la historia contada, sino a la misma concepción unitaria de la obra. Los propios clásicos hablaban de monere et delectare como fines de la creación literaria; no hay que perderlos de vista: la enseñanza la llevan puesta los propios textos, pero hay que lograr que aflore en ellos la diversión para el lector actual. Utilizaré como ilustración de esa exposición teórica las dificultades que he encontrado en la tarea de llevar a cabo algunas de mis ya numerosas adaptaciones de clásico…
Remarks on the environmental adaptation of man.
1971
In this paper the geographical variability of some morphological, physiological and serological traits of man is discussed with respect to the question, how far this variability can be considered as the result of selective adaptation processes. Though there is already some evidence supporting such an assumption, much more detailed and exactly planned research is necessary to clear the indubitable relations between the distribution patterns of anthropological traits and the various environmental conditions of human biotops. Particularly much more work is required to understand the causative mechanisms on which these relations are based.
Spectral adaptation of hyperspectral flight lines using VHR contextual information
2014
Abstract: Due to technological constraints, hyperspectral earth observation imagery are often a mosaic of overlapping flight lines collected in different passes over the area of interest. This causes variations in aqcuisition conditions such that the reflected spectrum can vary significantly between these flight lines. Partly, this problem is solved by atmospherical correction, but residual spectral differences often remain. A probabilistic domain adaptation framework based on graph matching using Hidden Markov Random Fields was recently proposed for transforming hyperspectral data from one image to better correspond to the other. This paper investigates the use of scale and angle invariant…
