The point of view and the remedy which is suggested are both unorthodox. The point of view is one of law and literature; the remedy is taken from law and economics. Even if the </span><span lang="en-GB">paper</span><span lang="en-GB"> agrees that the proposal of introducing both a social contribution on robots and a new regulation via apps follows on from the right question, it holds that such measures are not necessarily the right answer. In fact, since these would ‘anthropomorphise’ robots and algorithms, it would inevitably be useless, similar to any increase in social contributions. Conversely, the article proposes a radical change in perspective, deeming that social protection in the digital era requires new relationships between ‘every’ market and ‘the’ social justice. For the latter purpose, the chapter proposes to break the two alternative dichotomies of Bismarckian/Beveridgean systems of social provisions and that of employee/independent-contractor (at the level of regulation through the law). In this regard, such change is reached without extending the regulation of employees. Consequently, the chapter proposes to introduce a new ‘uniform’ and indirect financial system for protections for those who are not in a standard employment relationship. Such a ‘uniform’ financing device for social contributions is based on the ‘added value’ of work rather than (the opposite of how it actually is) based either on the wage of an employee or on the earnings of the self-employed. This way, the shifting boundaries of contracts between companies or firms and employees or workers, or even the self-employed, can be overcome because no particular contract is needed for protection.</span></em></span></span></p> 2020-12-07T00:00:00+00:00 ##submission.copyrightStatement## http://swps.unipa.it/index.php/swps/article/view/29 The Marsala Wine Consortium.

The aim is to review selection criteria, namely information criteria and hypothesis testing, and to propose a novel application in the context of students' careers in higher education. The performance of the selection criteria is assessed through simulation studies. Furthermore, we investigate the relationship between University students' performance and one of its main determinants, finding out that this relationship is actually broken-line.</p> 2020-10-24T00:00:00+00:00 ##submission.copyrightStatement## http://swps.unipa.it/index.php/swps/article/view/33 CoViSTAT19 - ANALISI DATI E PREVISIONI SU COVID-19 2021-01-26T18:30:54+00:00 Andrea Consiglio andrea.consiglio@unipa.it Vito M.
