Comment on Using Criminal Punishment to Serve Both Victim and Social Needs

Haley comments on the argument underlying the article by Erin Ann O\u27Hara and Maria Mayo Robbins, which emphasizes on victim-offender mediation (VOM). By expanding the frame of reference, restorative justice can be defined as a paradigm whose scope encompasses more than VOM and whose emphasis includes the needs of society and offenders as well as victims. Restorative justice involves a wide variety of processes and programs that are more apt to restore both those who commit and those who suffer wrongs. It includes children at risk programs, drug courts, violence-treatment programs, as well as VOM programs. It also includes efforts to assist former convicts returning to the community to engage in constructive lifestyles and sustainable roles in families, workplaces, and neighborhoods

Reflections on becoming a teacher and the challenges of teacher education

In this lecture, the context and conditions of becoming a teacher from the time of being selected into the programme, through the process of training and being retained to teach are discussed within the framework of Teacher Education in Nigeria. First, the concepts and the history of teacher education are examined. Then, some critical issues as well as my personal research efforts on teacher education are discussed. Finally, recommendations for meeting the challenges of Teacher Education in Nigeria are made

Urban droughts and floods in Maiduguri: twin hazards of a variable climate

Maiduguri, an important city in the Sudano-Sahelian zone of West Africa, experiences both drought and floods. Although droughts are more popular, floods are a seasonal occurrence in parts of the city in the average rainy season. Both hazards exert a heavy toll on their victims. Present response to the hazard problems is characterised by a fire-fighting approach which does little about future occurrence. Much of the perception and response is spiritual and stops short of needed structural and organisational programmes for effective mitigation of hazards. Future occurrences of drought and flood may have more adverse effects as land use in the city becomes more complex and agricultural and water supply system comes to depend heavily on surfacial sources. Future effects will also depend on the socio-economic conditions of the people at risk and the capacity of those who help them. Governments and people need to work together to reduce drought and flood hazards

Theoretical framework to surpass the Betz limit using unsteady fluid mechanics

The Betz limit expresses the maximum proportion of the kinetic energy flux incident on an energy conversion device that can be extracted from an unbounded flow. The derivation of the Betz limit requires an assumption of steady flow through a notional actuator disk that is stationary in the streamwise direction. The present derivation relaxes the assumptions of steady flow and streamwise actuator disk stationarity, which expands the physically realizable parameter space of flow conditions upstream and downstream of the actuator disk. A key consequence of this generalization is the existence of unsteady motions that can, in principle, lead to energy conversion efficiencies that exceed the Betz limit not only transiently but also in time-averaged performance. Potential physical implementations of those unsteady motions are speculated
