At present it is no longer merely scientists and experts but broad strata of the public who are beginning to recognize that the greatest danger ever to threaten mankind as a whole has arisen for the first time in history, since the very existence of Homo sapiens as a biological species has been placed in question.

In this study, complex dynamics of Briggs–Rauscher reaction system is investigated analytically and numerically. First, the Briggs–Rauscher reaction system is reduced into a new nonlinear parametric oscillator. The Melnikov method is used to derive the condition of the appearance of horseshoe chaos in the cases ω = Ω and ω ≠ Ω. The performed numerical simulations confirm the obtained analytical predictions. Second, the prediction of coexisting attractors is investigated by solving numerically the new nonlinear parametric ordinary differential equation via the (...) fourth-order Runge–Kutta algorithm. As results, it is found that the new nonlinear chemical system displays various coexisting behaviors of symmetric and asymmetric attractors. In addition, the system presents a rich variety of bifurcations phenomena such as symmetry breaking, symmetry restoring, period doubling, reverse period doubling, period-m bubbles, reverse period-m bubbles, intermittency, and antimonotonicity. On the contrary, emerging chaotic band attractors and period-1, period-3, period-9, and period-m bubbles routes to chaos occur in this system. (shrink)

Since the last several years of the life of King Hassan II, Morocco slowly moved from authoritarian rule to a managed democracy. As a result of this gradual political liberalization, religious groups as well as secular ones formed political parties. Islamists have already won seats in the parliament and they are expected to gain nearly half the number of seats in the coming elections. Equally significant is the increased presence of human rights and non-government organizations and the emergence of independent (...) and party-affiliated newspapers and other media outlets. In this article, I focus on the prospects of seeing a free press emerging in Morocco given the pressures exerted by official and non-official authorities. I argue that government interventions stifle freedom of expression and weaken civil society. This study focuses exclusively on Moroccan Arabic and French language print media. (shrink)
