The strategic role of the corporate social responsibility and circular economy in the cosmetic industry

In the literature, circular economy (CE) and corporate social responsibility (CSR) are increasingly interconnected concepts. Turon at al. (2016) consider CE the guidelines of conduct for designing and developing good CSR strategies. In particular, the corporate management philosophy needs to be translated into mandatory CSR reports that better frames circular economy objectives by identifying and communicating actions to achieve sustainable development goals. The purpose of this paper is to explore a number of CSR reports in order to understand if cosmetic multinationals' (MNC) nonfinancial reporting is focused on the concept of circular economy and if CSR reports ensure an adequate level of disclosure to circular strategies. Moreover, the paper highlights the advantages that arise by converging the concepts of CSR and CE. The originality of this paper lies on providing evidence on "how" MNC are implementing a circular model. This paper contributes to our understanding on the relation between CSR and CE; it assesses the state of the art of circular strategies in MNC and proposes a consolidation of the concept of CE in terms of sustainable strategic and managerial practices communicated to the market by CSR reports. Moreover, it brings MNC to a better understanding of the ways to communicate their new circular business model. The analysis reveals a good level of attention by MNC to circularity in drafting their CSR reports that in many cases are able to describe objectives and actions that embrace multiple dimensions

European Perceptions of Autonomous and Robotized Cars

This article explores users\u2019 attitudes, perceptions, views, and emotions toward car automation and robotization, two processes increasingly affecting society in different ways\u2013\u2013namely, the rise of autonomous and robotized cars (and vehicles in general) and the increasing level of robotization of current cars. To address these questions, we investigated the feeling of trust and comfort toward driverless cars among Europeans using two Eurobarometer surveys. Making use of two representative samples of the European population, we aimed to explore citizens\u2019 attitudes and opinions about automation and digitization. The two surveys involved, respectively, 27,801 and 27,901 participants from all EU-28 countries. Furthermore, we investigated, in Northern Italy, the perception of robotization of cars and other technologies of everyday use, as well as the attitudes and opinions of children and preteens (n = 740), and adolescents (n = 801)\u2014 relevant social groups not covered in the Eurobarometer surveys

Integrability and strong normal forms for non-autonomous systems in a neighbourhood of an equilibrium

The paper deals with the problem of existence of a convergent "strong" normal form in the neighbourhood of an equilibrium, for a finite dimensional system of differential equations with analytic and time-dependent non-linear term. The problem can be solved either under some non-resonance hypotheses on the spectrum of the linear part or if the non-linear term is assumed to be (slowly) decaying in time. This paper "completes" a pioneering work of Pustil'nikov in which, despite under weaker non-resonance hypotheses, the nonlinearity is required to be asymptotically autonomous. The result is obtained as a consequence of the existence of a strong normal form for a suitable class of real-analytic Hamiltonians with non-autonomous perturbations.Comment: 10 page

Scaling up MIMO Radar for Target Detection

This work focuses on target detection in a colocated MIMO radar system. Instead of exploiting the »classical' temporal domain, we propose to explore the spatial dimension (i.e., number of antennas M) to derive asymptotic results for the detector. Specifically, we assume no a priori knowledge of the statistics of the autoregressive data generating process and propose to use a mispecified Wald-type detector, which is shown to have an asymptotic χ-squared distribution as M → ∞. Closed-form expressions for the probabilities of false alarm and detection are derived. Numerical results are used to validate the asymptotic analysis in the finite system regime. It turns out that, for the considered scenario, the asymptotic performance is closely matched already for M ≥ 50

Persistence of Diophantine flows for quadratic nearly-integrable Hamiltonians under slowly decaying aperiodic time dependence

The aim of this paper is to prove a Kolmogorov-type result for a nearly-integrable Hamiltonian, quadratic in the actions, with an aperiodic time dependence. The existence of a torus with a prefixed Diophantine frequency is shown in the forced system, provided that the perturbation is real-analytic and (exponentially) decaying with time. The advantage consists of the possibility to choose an arbitrarily small decaying coefficient, consistently with the perturbation size.Comment: Several corrections in the proof with respect to the previous version.
