    Oltre lo smart working : modelli di lavoro agile e sostenibile

    No full text
    La parola smart working è diventata parte dei nostri dialoghi, ma è spesso legata al solo lavoro in remoto. Al contrario le aziende stanno sperimentando nuovi modelli di collaborazione con un'apertura mentale al dialogo ed al confronto. Questo libro nasce dall'obiettivo di raccogliere le prospettive di opinion leader di rilievo e le testimonianze di chi quotidianamente porta avanti le politiche relative alle persone. Molteplici sono i tasselli su cui prende forma questo nuovo "movimento" della cultura del lavoro: #workation, #contaminazione intergenerazionale, #delega e fiducia, #lavoro remotizzato e robotizzato, #employee experience, #responsabilità, #ascolto, #self-leaderhip, #work life integration. Grazie a Paolo Iacci, Gabriele Gabrielli, Franco Amicucci e Luca Solari vengono messe a disposizione quattro prospettive dello sviluppo per una vera introduzione del lavoro agile nella realtà lavorativa italiana, toccando i punti nevralgici dell'azienda (formazione, leadership, organizzazione e purpose) e offrendo agli HR una nuova consapevolezza. A questi presupposti Smart Working Magazine e HR Link, da tempo impegnate nella diffusione della cultura del lavoro agile, hanno voluto aggiungere e raccogliere prospettive e testimonianze da chi quotidianamente esprime in azioni concrete questo nuovo modo di concepire il lavorare. Un'importante riflessione sul concetto del lavoro oggi e sulle sue possibili applicazioni, come strumenti di miglioramento delle organizzazioni e della vita lavorativa degli smart worker

    Minimal Self-Immolative Probe for Multimodal Fluoride Detection

    No full text
    Two single-molecule, self-immolative fluoride probes, namely tert-butyldimethylsilyl-protected 2- and 4-difluoromethylphenol, are described. Compared to similar systems previously described, the probes are characterized by a simpler structure and straightforward, two-step preparation. Nevertheless, they allow the detection of fluoride ions at micromolar concentration by the naked eye, UV−vis absorption, and fluorescence. A detailed investigation of the self-immolative reaction reveals that the rate-limiting step is the release of the first fluoride ion from the difluoromethylphenolate intermediate. Moreover, the mutual position of the difluoromethyl- and tert-butyldimethylsilyl-protected residues has a relevant effect on the reactivity. Likely, a CF2H−O hydrogen bond in the 2-isomer increases the reactivity of the silyl ether toward hydrolytic cleavage but also stabilizes the phenolate intermediate, slowing the release of fluoride ions

    Pietro Gabrielli dopo il processo ai Bianchi (1692-1704). I frequentatori del “salotto” di un eretico prigioniero nella fortezza di Perugia

    No full text
    Pietro Gabrielli was a cleric tried by the Roman Inquisition for being the patron of a group of libertine intellectuals in 1692. He was sentenced to life detention in the fortress of Perugia. This article analyses his time in prison and describes how he managed to continue his studies with the intellectuals present in Perugia between 1702 and 1704. Gabrielli dis¬cussed with Antonio Felice Marsili, Alessandro Burgos and Domenico Lazzarini during this period of time. Therefore, he was in contact with a heterogeneous group of professors and clergymen, that were committed to reform the Universities’ teachings in the Papal States. This article has reconstructed the activities of these intellectuals, describing how they were the branch of a much larger movement, that created a precedent for the successive enlightened reforms

    Entanglement and Bell Inequality Violation in B → ϕϕ Decays

    No full text
    The decays of the B meson into vector mesons, observed during the LHCb experiment, provide an ideal laboratory to investigate particle physics phenomena with quantum information theory methods. In this article, we focus on the decays yielding a pair of ϕ mesons to investigate the presence of entanglement in the spin correlations of the system and quantify the amount of Bell inequality violation it entails. Our results show that the present LHCb data allow access to entanglement and to the Bell inequality violation with a significance exceeding the 5σ threshold in both the cases. This demonstrates that the strong and electroweak interactions responsible for the B meson decay act as a source of entanglement and the quantum mechanics nature of high-energy phenomena. Particular attention is paid to the assessment of loopholes: deficiencies in the experimental setup which could invalidate the results of the Bell test

    Towards a Sustainable Internet of Sounds

    No full text
    The Internet of Sounds (IoS) is an emerging research area at the intersection of engineering fields and humanities including computing, communication technology, audio signal processing, acoustic monitoring, music and arts. Although this research field is expected to have beneficial impacts on society through entertainment, creativity, well-being, monitoring and security, it is paramount to be aware of the adverse impact of current technology on the environment in terms of greenhouse gases emissions, pollution and soil consumption. In this study we provide a survey of the environmental issues produced by current information and communication technology (ICT) and relate these to the use cases that the IoS envisions. On the basis of this survey, we identify some key aspects to reduce the footprint of IoS services and products and then we provide suggestions to make advancements in IoS environment-aware

    Light Mesons and Muon Radiative Decays and Photon Polarization

    No full text
    We systematically compute and discuss meson and muon polarized radiative decays. Doubly differential distributions in terms of momenta and helicities of the final lepton and photon are explicitly computed. The undergoing dynamics giving rise to lepton and photon polarizations is examined and analyzed in the soft and hard region of momenta. The particular configurations made by right-handed leptons with accompanying photons are investigated and interpreted as a manifestation of the axial anomaly. The photon polarization asymmetry is evaluated. Finiteness of polarized amplitudes against infrared and collinear singularities is shown to take place with mechanisms distinguishing between right- and left-handed final leptons. We propose a possible test using photon polarization to clarify a recently observed discrepancy in radiative meson decays

    An assessment of the impact of possible CAP reform scenarios on Romanian agriculture

    No full text
    Using a simplified model, with key-variable the prices of two different possible scenarios of CAP reform after 2013 (moderate and radical), this paper present a comparison between the price effects of implementation of each reform scenario at 2015 horizon on Romanian agriculture. This short analysis shows that, under the presented hypotheses, the net welfare effect, due to the price changes, for the selected products, is positive in both reform scenarios, yet greater in the case of the radical reform. Integrated in the large context of Romanian development, it seems that the influence of CAP reform upon agriculture and rural areas will be most likely a gradual one: an interpenetration between the two scenarios is foreseeable, starting with the moderate reform that will dominate the period around 2013, the reform measures acquiring a more radical character afterwards.CAP reform, Romania, welfare effects, Agricultural and Food Policy,

    Rich, Sturmian, and trapezoidal words

    No full text
    In this paper we explore various interconnections between rich words, Sturmian words, and trapezoidal words. Rich words, first introduced by the second and third authors together with J. Justin and S. Widmer, constitute a new class of finite and infinite words characterized by having the maximal number of palindromic factors. Every finite Sturmian word is rich, but not conversely. Trapezoidal words were first introduced by the first author in studying the behavior of the subword complexity of finite Sturmian words. Unfortunately this property does not characterize finite Sturmian words. In this note we show that the only trapezoidal palindromes are Sturmian. More generally we show that Sturmian palindromes can be characterized either in terms of their subword complexity (the trapezoidal property) or in terms of their palindromic complexity. We also obtain a similar characterization of rich palindromes in terms of a relation between palindromic complexity and subword complexity
