Abstract: This study empirically examines the everyday problem of corrupt policing and other related abuses in Nigeria, and how these deviant behaviours engender public cynicism towards the law. In any democratic society, police officers are expected to be accountable for their actions and inactions. But the perennial problem in Nigeria is that the police are not accountable to anyone. The history of Nigeria policing is littered with accounts of deviance, malevolent attitudes towards the public and failures of the police organization in detecting or disciplining errant officers. Using a s le of 462 participants from a cross-sectional survey, this study examines whether actual or vicarious experiences of police deviance are likely to predict public cynicism towards the law. This current study corroborates previous assertions that the relationship between the police and the public in Nigeria is poor and that police deviance engenders cynicism towards the law. Implications for policymaking and law-abiding behaviour are discussed.

Abstract: In recent years, harvesting energy from ubiquitous ultralow-frequency vibration sources, such as biomechanical motions using piezoelectric materials to power wearable devices and wireless sensors (e.g., personalized assistive tools for monitoring human locomotion and physiological signals), has drawn considerable interest from the renewable energy research community. Conventional linear piezoelectric energy harvesters (PEHs) generally consist of a cantilever beam with a piezoelectric patch and a proof mass, and they are often inefficient in such practical applications due to their narrow operating bandwidth and low voltage generation. Multimodal harvesters with multiple resonances appear to be a viable solution, but most of the previously proposed designs are unsuitable for ultralow-frequency vibration. This study investigated a novel multimode design, which included a bent branched beam harvester (BBBH) to enhance PEHs’ bandwidth output voltage and output power for ultralow-frequency applications. The study was conducted using finite element method (FEM) analysis to optimize the geometrical design of the BBBH on the basis of the targeted frequency spectrum of human motion. The selected design was then experimentally studied using a mechanical shaker and human motion as excitation sources. The performance was also compared to the previously proposed V-shaped bent beam harvester (VBH) and conventional cantilever beam harvester (CBH) designs. The results prove that the proposed BBBH could harness considerably higher output voltages and power with lower idle time. Its operating bandwidth was also remarkably widened as it achieved three close resonances in the ultralow-frequency range. It was concluded that the proposed BBBH outperformed the conventional counterparts when used to harvest energy from ultralow-frequency sources, such as human motion.
