Osservazioni sull’industria litica di Fimon − Molino Casarotto
No full textMolino Casarotto, nelle Valli di Fimon (Colli Berici, Veneto), è un sito del Pieno Neolitico, riferito alla fase antica (stile geometrico-lineare) della Cultura dei Vasi a Bocca Quadrata. Ceramica, industria litica su selce, industria litica su pietra verde non lo diff erenziano dagli altri siti coevi dell’Italia settentrionale. Si distingue invece per la sua collocazione in prossimità di un lago, per l’adattamento delle
strutture abitative all’ambiente umido, per lo sviluppo di un’economia legata soprattutto allo sfruttamento delle risorse off erte dal lago e alla caccia, nella quale le attività produttive hanno un ruolo secondario. Di queste caratteristiche si dovrà tener conto nella definizione del Pieno Neolitico dell’area padana. Il nostro contributo è dedicato in particolare all’industria litica su selce: va sottolineato che i Neolitici di Molino Casarotto non hanno utilizzato le più vicine selci Berico-Euganee, ma si sono costantemente riforniti dai Lessini centro-occidentali, ove si trovano risorse litiche particolarmente idonee e ricercate per la produzione di un’industria macrolitica caratterizzata da forte laminarietà.SUMMARY − Molino Casarotto, in the Fimon Valleys (Berici Hills, Veneto), is a site of the Full Neolithic period, referring to the ancient phase (geometric-linear style) of the Culture of Square Mouthed Vases. Ceramics, lithic industry on fl int, lithic industry on greenstone do not diff erentiate it from other contemporary sites in northern Italy. Instead, it stands out for its location near a lake, for the adaptation of housing structures to the humid environment, for the development of an economy linked to the exploitation of the resources off ered by the lake and hunting, in which productive activities have a secondary role. ese characteristics must be taken into account in defi ning the Full Neolithic of the Po Valley. Our contribution is dedicated in particular to the lithic industry on fl int: it should be emphasized that the Neolithics of Molino Casarotto did not use the closest Berici and Euganei fl ints, but were constantly supplied by the central-western Lessini, where there are lithic resources particularly suitable and sought after for the production of a macrolithic industry characterized by strong laminariness
Imparare a leggere: i meccanismi psicofisiologici
No full textDyslexya isn’t a simple perceptive deficit but a more complex one linked to the malfunctioning of high cognitive functions.
An early diagnosis is necessary in order to recover a good reading ability and good social relations. The author analyses the various interpretative hypothesis regarding this heterogeneous disease which involves different neuronal and functional circuits.
Basically two main theoretical models are described, both focalizing the attention to the neurophysiological damage (thanks to the new diagnostic imaging techniques) and to the macroscopic anatomical damage of specific areas of the brain. The role of neuropsychology is enhanced through the study of the brain’s electrical and muscular reactions following reading aloud visible alphabet letters

Dynamic time warping in the analysis of event-related potentials
No full textThe aim of this article is to compute reliable templates of event-related potentials (ERPs) for homogeneous groups of subjects and to automatically quantify the morphological characteristics of the ERPs. We developed a method based on dynamic time warping (DTW). The method was applied to ERPs recorded from normal and dyslexic children during two reading tasks. We found that characteristic latency and amplitude changes of ERP components are due to task and pathology. Our results support the idea that dyslexia involves different and complex cerebral functions aside from the language system. This mathematical approach provides reproducible analysis criteria that are crucial for the reliability of ERP analysis
Formação de rede de empresas de tecnologia da informação com base na análise da cadeia de valor
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia de Produção, Florianópolis, 2010Este trabalho propõe-se a identificar, dentro da cadeia de valor de empresas de base tecnológica da Grande Florianópolis, pontos e formas de cooperação, com base no conceito de redes cooperativas de pequenas e médias empresas. Inicialmente é feito um levantamento da bibliografia sobre o assunto, tratando de temas como benchmarking, redes de pequenas e médias empresas, cadeia de valor e metodologias para formação de consórcios e identificação de pontos e formas de cooperação. Utilizando-se como base, uma metodologia já desenvolvida em linha de pesquisa do Programa de Pós-Graduação em Engenharia de Produção da Universidade Federal de Santa Catarina que, por meio de benchmarking e análise da cadeia de valor, possibilita realizar um diagnóstico do desempenho das empresas e localizar os possíveis pontos de cooperação, desenvolveu-se uma metodologia derivada, voltada a redes de empresas de base tecnológica, adequando-se, com isso, o questionário padrão. A pesquisa foi realizada num grupo de quatro empresas de tecnologia na região da Grande Florianópolis, que estão em fase de criação de uma rede/consórcio. Com a aplicação da metodologia foi possível descrever a cadeia de valor de cada uma das empresas estudadas e principalmente identificar os pontos de cooperação dentro do grupo. Estes pontos, bem como a metodologia, foram validados através da aplicação de um segundo questionário buscando a concordância ou não do grupo sobre os resultados da pesquisa.This study aims to identify within the value chain of technology-based companies in Florianópolis points and forms of cooperation within the concept of cooperative networks of small and medium enterprises. First is a survey of the literature on the subject, dealing with topics such as benchmarking, networks of small and medium enterprises, and methods for forming consortia and the identification of points and forms of cooperation. It´s based on a methodology already developed in a research line in the Post-Graduation program in Production Engineering of Universidade Federal de Santa Catarina, which uses benchmarking and analysis of the value chain, to perform a diagnosis of business performance and locate possible points of cooperation. A new questionnaire was developed. The application was performed in a group of four technology companies in the Florianópolis Region. With the application of the methodology was possible to describe the value chain of each of the companies studied and identify areas of cooperation within the group. These points, as well as the methodology have been validated by applying a second questionnaire seeking the group's agreement or disagreement on the results of research

The psychophysiology of reading
No full textEarly identification of dyslexiawould be fundamental to prevent the negative consequences of delayed treatment in the social, psychological and occupational domains. Movement-related potentials of dyslexic children are characterized by inadequate ability to programmovements and reduced capacity to evaluate their performance and to correct their errors. Reading-related potentials recorded during different reading conditions elicit a series of positive and negative components with specific functional meaning and with a characteristic spatial-temporal pattern. These reading-related potentials, when analyzed with sLORETA, show significantly different patterns of activation when comparing self-paced reading aloud to passive viewing of single letters. Comparison of fMRI and sLORETA during both tasks showed that the cortical region with the widest inter-modality similarities is the middle-superior temporal lobe during self-paced reading aloud. Neuropsychological studies have shown the existence of clinical subtypes of dyslexia; these studies have been confirmed by the results of ICA applied to the EEG. Dyslexia can be defined as a disorder of programming and integrating ideokinetic elements, associated with a deficiency in the fast processing and integration of sensory information, with reduced efficiency of error systems analysis. Each of these phenomena occurs at different levels of the central nervous system and at different times
