Journal of International Women's Studies

Nigerian women account for almost half of the country’s population, yet they represent a minuscule percentage of elected positions. Many scholars have attributed this to the patriarchal system inherent in Nigeria. This study, however, submits that the rate at which women support women politicians during elections is a major contributing factor to unequal gender representation in Nigerian politics. The concept of the glass ceiling and postcolonial theory guided the explanatory framework for this study. The study was conducted among women within voting age in Ibadan, in southwestern Nigeria. The study adopted a mixed-method design to generalize and gain deep insights. …

This work presents a general framework for developing a multi-parameter 1-D chaotic system for uniform and robust chaotic operation across the parameter space. This is important for diverse practical applications where parameter disturbance may cause degradation or even complete disappearance of chaotic properties. The wide uninterrupted chaotic range and improved chaotic properties are demonstrated with the aid of stability analysis, bifurcation diagram, Lyapunov exponent (LE), Kolmogorov entropy, Shannon entropy, and correlation coefficient. We also demonstrate the proposed system’s amenability to cascading for further performance improvement.
