    Commentario breve alla legislazione sugli appalti pubblici e privati.

    No full text
    L'opera si sviluppa come un commento delle disposizioni del Codice Civile dedicate al contratto d'appalto (artt. 1655-1677) ed un commento analitico del Codice dei Contratti Pubblici (D. Lgs. 12 aprile 2006, n. 163 e successive modifiche). Il commentario è aggiornato a tutte le novità apportate dal terzo decreto legislativo correttivo al Codice dei Contratti Pubblici (D.Lgs. 11 settembre 2008, n. 152). Il commento alle disposizioni del Codice civile, giovandosi della vasta elaborazione dottrinale e giurisprudenziale della fattispecie codicistica, offre un'efficace trattazione delle più importanti questioni, pratiche e teoriche, che investono la materia dell'appalto privato. Il commento al Codice dei Contratti Pubblici, persegue l'obiettivo di offrire una sistematica interpretazione delle innovazioni legislative, anche alla luce delle prassi consolidatesi nel vigore della pregressa disciplina, dettata da un sistema di fonti frastagliato. In Appendice è contenuta la nuova versione del Regolamento attuativo

    La filiera professionale dell'educazione : mappatura dei settori e dei servizi alla persona a partire dal caso paradigmatico della regione puglia

    Nasciamo incompiuti. L’educazione è un fattore fondamentale della nostra compiutezza umana nel corso della vita e, pertanto, uno dei diritti umani inalienabile. In quanto tale essa è inizialmente educazione informale che ci accompagna in tutte le esperienze quotidiane. Le società industriali hanno individuato nell’educazione formale, garantita dall’insegnante nella scuola per tutti, la maturazione dei giovani. Nell’attuale società globale l’educazione informale è sempre più incisiva nei giovani e negli adulti: chi se ne fa carico? Gli educatori e i formatori, e a seguire gli esperti della formazione e i pedagogisti: vengono preparati in particolare nelle Facoltà di Scienze della Formazione a realizzare interventi educativi e formativi non formali nei più diversi contesti e problemi della vita individuali e sociali, occupandosi in via prioritaria dei giovani e degli adulti espulsi dalla scuola e dal lavoro, emarginati dalla società, discriminati, tra l’altro, per le loro diversità biopsichiche, culturali, condizione socio-economica. La professionalità degli educatori dall’infanzia all’età avanzata e dei formatori al e nel lavoro non è stata ancora riconosciuta in Italia e, non poche volte i loro ambiti di intervento sono coperti impropriamente da altri operatori. Il libro Professioni educative e formative, risultato della ricerca interuniversitaria e pluriennale PRIN (DM 1175/2007), è il primo a fare il punto di tali professioni in Italia e ad indicare l’indispensabile e dovuto processo normativo del loro riconoscimento, come richiesto dalle direttive dell’Unione Europea. Il libro è un testo fondamentale per quanti si preparano a svolgere e svolgono attività educative e formative, oltre che per i gestori e i responsabili di politiche educative e formative

    In-situ calibration of pollutant measuring-units by means of remotely-controlled traveling standards

    No full text
    The increasing diffusion of pollutant measuring units which are installed over wide areas along with the short calibration interval of several sensors for pollutant quantities requires new calibration infrastructures to be developed. This paper describes an attempt to develop an innovative calibration system which is based on traveling standards and which does not require a unit to be removed from the measuring site during the calibration process. The calibration system is based on a simple traveling standard, which is composed of one or more gas cylinders with known standard gas mixtures, a cell with standard sensors and a network-enabled contro-unit, which allows the entire standard to be remotely exercised. A prototype of the proposed system is described and the initial results obtained in the case of sensors reported

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Cross-Talk Effects in the Uncertainty Estimation of Multiplexed Data Acquisition Systems

    Full text link
    This paper deals with the analysis of multi-channel data-acquisition systems with the aim of identifying and combining the main uncertainty contributions according to the GUM framework. Particular attention has been paid towards cross-talk effect, which could be an important uncertainty contribution in multiplexed data-acquisition systems. The uncertainty analysis is described for three commercial data acquisition devices highlighting that cross-talk specifications are often not suitable for a reliable uncertainty estimation in operating conditions. For this reason, an experimental set-up has been arranged to fully characterize the inter-channel effects of the investigated devices. The obtained results have highlighted that a proper characterization of a data-acquisition system is effective in estimating the actual performance at the frequency of interest and in the operating conditions for the source resistance and the input-channel configuration. Eventually, a customized procedure has been proposed that is effective in correcting the cross-talk effects also in very severe conditions of inter-channel disturbance

    Uncertainty analysis of degradation parameters estimated in long-term monitoring of photovoltaic plants

    No full text
    This paper deals with the uncertainty analysis of parameters estimated during long-term monitoring of photovoltaic plants. A specifically developed data-acquisition system is briefly described, which has been conceived to be easily calibrated and, if necessary, adjusted to compensate for measuring-chain drifts, in order to assure the traceability of the estimated parameters. The measurement capabilities of the acquisition system are reported in terms of measured quantities and expected uncertainty. Results that refer to a three-year monitoring of ten photovoltaic plants based on different technologies and architectures are reported. The obtained uncertainty is suitable to distinguish the behavior of the different plants, thus allowing a preliminary comparison to be performed among technologies and architectures. Experimental results highlight an important difference between crystalline silicon devices and thin film technologies in regards to degradation

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
