    Description: The article identifies the extent to which the most valuable Romanian companies practice corporate social responsibility (CSR) and its beneficiaries. It describes the main areas of action and specific instruments of intervention. The data analysed cover the top 100 Romanian companies, as ranked by Ziarul Financiar. The corporate website of each company was analysed and subsequently codified on multiple variables. The results outline the fact that firms engage in CSR activities to a relatively high extent (49% of the companies). They adopt a vision of corporate social responsibility exclusively centred on the firm and the competitive advantages that derive from CSR activity. The wider community is represented as the primary stakeholder and beneficiary, whilst those stakeholders thought to influence the profit-making goals to a lesser extent are more often than not overlooked. Finally, companies prefer inexpensive intervention instruments and prove weak coordination with others social and political actors.

    Description: In this manuscript we investigate the existence of the fractional finite difference equation (FFDE) Δμ−2μx(t)=g(t+μ−1,x(t+μ−1),Δx(t+μ−1)) via the boundary condition x(μ−2)=0 and the sum boundary condition x(μ+b+1)=∑k=μ−1αx(k) for order 1

    Description: In this paper, based on fixed entropy, the adiabatic equation of state in fractal flow is discussed. The local fractional wave equation for the velocity potential is also obtained by using the non-differential perturbations for the pressure and density of fractal hydrodynamics.

    Description: Entropy, Vol. 19, Pages 681: Chaos in a Cancer Model via Fractional Derivatives with Exponential Decay and Mittag-Leffler Law Entropy doi: 10.3390/e19120681 Authors: José Gómez-Aguilar María López-López Victor Alvarado-Martínez Dumitru Baleanu Hasib Khan In this paper, a three-dimensional cancer model was considered using the Caputo-Fabrizio-Caputo and the new fractional derivative with Mittag-Leffler kernel in Liouville-Caputo sense. Special solutions using an iterative scheme via Laplace transform, Sumudu-Picard integration method and Adams-Moulton rule were obtained. We studied the uniqueness and existence of the solutions. Novel chaotic attractors with total order less than three are obtained.

    Description: Entropy, Vol. 19, Pages 375: A Novel Numerical Approach for a Nonlinear Fractional Dynamical Model of Interpersonal and Romantic Relationships Entropy doi: 10.3390/e19070375 Authors: Jagdev Singh Devendra Kumar Maysaa Al Qurashi Dumitru Baleanu In this paper, we propose a new numerical algorithm, namely q-homotopy analysis Sumudu transform method (q-HASTM), to obtain the approximate solution for the nonlinear fractional dynamical model of interpersonal and romantic relationships. The suggested algorithm examines the dynamics of love affairs between couples. The q-HASTM is a creative combination of Sumudu transform technique, q-homotopy analysis method and homotopy polynomials that makes the calculation very easy. To compare the results obtained by using q-HASTM, we solve the same nonlinear problem by Adomian’s decomposition method (ADM). The convergence of the q-HASTM series solution for the model is adapted and controlled by auxiliary parameter and asymptotic parameter n. The numerical results are demonstrated graphically and in tabular form. The result obtained by employing the proposed scheme reveals that the approach is very accurate, effective, flexible, simple to apply and computationally very nice.

    Description: In this paper, we propose a new type (n + 1)-dimensional reduced differential transform method (RDTM) based on a local fractional derivative (LFD) to solve (n + 1)-dimensional local fractional partial differential equations (PDEs) in Cantor sets. The presented method is named the (n + 1)-dimensional local fractional reduced differential transform method (LFRDTM). First the theories, their proofs and also some basic properties of this procedure are given. To understand the introduced method clearly, we apply it on the (n + 1)-dimensional fractal heat-like equations (HLEs) and wave-like equations (WLEs). The applications show that this new technique is efficient, simply applicable and has powerful effects in (n + 1)-dimensional local fractional problems.

    Description: In this work, we study the fractional order Lane-Emden differential equations by using the reproducing kernel method. The exact solution is shown in the form of a series in the reproducing kernel Hilbert space. Some numerical examples are given in order to demonstrate the accuracy of the present method. The results obtained from the method are compared with the exact solutions and another method. The obtained numerical results are better than the ones provided by the collocation method. Results of numerical examples show that the presented method is simple, effective, and easy to use.
